Glitches are normal to appear in any game. Glitches and bugs are software errors that can cause drastic problems within the code and typically go unnoticed or unsolved during the production of said software. These errors can be game caused or otherwise exploited until a developer/development team repairs them. Complex software is rarely bug-free or otherwise free from errors upon the first release. This article is a list of the glitches found in Plants vs. Zombies Heroes. If you think you found one that deserves to be on this page, feel free to add it.
Sometimes, when your Super-Block Meter is activated, it doesn't disappear but the Hero can still be take damage. This is simply a visual glitch. It occurs when plants or zombies use special abilities, such as Sergeant Strongberry as in this case, Grapes of Wrath, or if plants or zombies use bonus attacks, such as Re-Peat Moss.
Tomb Raiser Wrong Summon Glitch
Tomb Raiser Zombie zombie has a chance to summon Mixed-Up Gravedigger, which should not be possible as it does not have the Gravestone attribute.
Tomb Raiser Softlock Glitch
A continuation but separate glitch from the one above, Tomb Rasier Zombie can summon Mixed-Up Gravedigger when it deals damage to the Plant Hero. When this occurs, the game will softlock and the Fight phase will never end. Neither player can concede, resulting in a never ending match.
Electric Boogaloo's Animations Glitch
Electric Boogaloo's animations are severly glitched. This ranges from going faster or slower than normal, as well as reacting to hits late. It is unknown what makes this happen.
No Defeat animation Glitch
After the 1.6.27 update, the Defeat animation can now appear earlier than when the Hero explodes. But when both plants Team-Up hits the Zombie Hero, they can cancel the defeat animation. The first Plant must finish the opponent hero's health to 0 and the Plant Team-Up will continue the attack to cancel the defeat animation. And the opponent hero gets defeated without the defeat animation, even after the game ends.
I can't play any zombie card and 10 second turn Glitch
If a player tries to save a Superpower trick card when lagging. It will not go to player's hand and next turn. The player cannot play any Zombie and automatically press the next turn button. When it's time for tricks, the player will only have 10 seconds to play and can still play Superpower trick card for free.
Move a Dead Plant Glitch
If a Portal Technician and Sky Shooter is destroyed and spawns Sumo Wrestler. The Sky Shooter can still be moved even the health is 0. If you moved another plant, it still cannot move until Sky Shooter is fully destroyed.
Missing HUD Glitch
If Mixed-up Gravediger is played and a non-amphibious zombie appears in the water lane, when bounced it will be missing the card details and the card background itself.
Block Meter Glitch
Sometimes the block meter will be fully charged, but no super block will happen. Therefore the player will get no more blocks. Block meter was still charged even after defeat. Has only been seen with Citron.
Playing with Fire Glitch
In the 39th zombie mission boss, the music will become higher pitch. This is because of the preplaced plants and zombies.
Collection Music Glitch
When coming back to the main menu, the key of the music may be raised. This applies for the online and Collection music. However, in Collection, there are 2 music pieces being played, one with the higher key and the regular.
Undead Boosting Glitch
If a fighter with a self-boosting effect activates said effect at zero health, it will still live if its health was boosted.
Duplicated Reward Glitch
After you get a higher rank (or have been promoted to a higher league), play Casual and beat it. After you beat it, you will get a notification that you ranked up and it show that you will get an amount of gems, and even it show that you have been promoted to a higher league and then give you another amount of gems. But if you checked again, no reward was given.
Pink Texture Glitch
Sometimes, when you lock your phone while your game is on (or open the notifications while playing), you will get a very weird glitch that will make the Heroes texture in Collection, plant background texture, about section and ranked image become pink. This is possibly because of broken textures, and they are then replaced with pink texture, similar to Plants vs. Zombies 2 where textures are replaced with either sun sprites or pink textures with a black X.
Selfish Engineer Glitch
If a science zombie deals damage, but dies in the process of a Zombot Drone Engineer to the immediate right buffing said science zombie, the Drone Engineer will receive the buff. It seems to be a visual glitch.
Phantom Electrician glitch
Similiar to the Seedling to Wild Berry Glitch, if there's a Headstone Carver in the field and then an Electrician is revealed from a Gravestone, then does a Bonus Attack to trigger a Potato Mine or Hothead leading to destroy the Electrician, the Headstone Craver will still boost the 'dead' Electrician even though it's dead. And because of that, the turn will last forever until the player concedes (if in a mission) or until one of the players concede (if in Multiplayer).
Unhanded Bounce glitch
Rarely, when a fighter is bounced by a card such as the Spring Bean or the Backyard Bounce, it will not return to its Hero's hand. Rather, it will be bounced off the playing field. However, it will still be able to attack and will be immune to damage in some cases.
Still-in-Hand Lane glitch
When a card is played, sometimes it will not be placed in its selected lane. Rather, it will be placed off of the playing field in the Hero's hand. The card acts like it is still in the selected lane, and will deal and take damage as normal. Although it appears similar to the Unhanded Bounce glitch, the card does not need to be bounced.
Undead card glitch
Rarely when a card's health is reduced to zero, it will not be defeated. Instead, it will just stay on the field and continue like they have health left. Attacking it again will destroy it.
Daily Quests glitch
There are some glitches involving the Daily Quests. When the player skips one quest, the new ones appear, but the old one is still there and can be completed, but it will not offer any reward. Skipping it the next day will make it disappear permanently, and no new quest is given.
Zero Health Hero
Unknown how this glitch starts, but sometimes the hero has 0 health. May be a visual glitch only.
A possible cause, is that the more damage glitch occurred and the enemy hero did not know, and didn't do the amount of damage needed to lower the real health. (Ex. the health might show zero when the hero actually has 5 left.)
Fighter size glitch
Sometimes, when a plant or zombie is placed on the field, it will be larger or smaller than it normally is. This also happens with cards.
Card has no strength when planted, but icon still showsIf a card with no strength points, such as the Prickly Pear, is boosted and had strength points added to it and is then bounced, its strength points will return to zero, but the strength icon will still be visible with 0 on the icon. This applies to both when the card is played and on its card.
Low health animation glitch
When a hero heals him/herself when they have low health and the health exceeds more than 5, they will continue to do their animation even though circumstances stand otherwise.
Seedling's Transformation Glitch
If the Plant Hero ends their turn by placing a Seedling and pressing the button, both heroes can see what the Seedling will transform into in the next turn.
Invisible Card Glitch
Sometimes, when the Plant or Zombie Hero places a card, it will be invisible, but still can absorb damage and attack normally.
Invisible Info Icon
When looking at the Yeti Lunchbox's Info there is a picture of a light, but the lunchbox itself does not appear to be visible.
A Fight to the Finish Line Water GlitchIn the 6th zombie mission, A Fight to the Finish Line, the 1st lane of water (the 2nd lane of the whole lawn) is actually a ground lane.
Out Of The Lawn GlitchSometimes in multiplayer, when a player plays a card it won't be placed where it is supposed to be, instead it will be placed out of the lawn.
Unclassified Info Glitch
When you scroll left from the first card in your deck, it shows a 3/3 card, a sun icon, and a brain icon. This is only a visual glitch since it serves no purpose in the game.
Electric Boogaloo's Shocking Moves Glitch
In the 26th Plant Mission Electric Boogaloo's Shocking Moves, you can't plant on the height lane. However, the zombie heroes can still plant on that lane. Still, you can still perform tricks that can affect zombies on the Heights lane, such as Big Chill, Iceberg Lettuce, or Squash. This increases total difficulty of the mission altogether.
Z-Mech Stolen Superpower Glitch
Super-Block Meter Glitch
Sometimes, when the super-block meter is almost full, and a hit makes a Super-Block, the super-block won't be registered, and the player won't get a card from it. Afterwards, when the hero is hurt, there will be no Super-Blocks as it still won't register.
Transparent Superpower Glitch
Sometimes when the Super-Block gives a superpower, some of the superpower appears to be white.
Soul Patch and Uncrackable Glitch
When Wall-Knight has a Soul Patch on the field and then he uses Uncrackable, the zombies that are supposed to hurt Wall-Knight that turn will still damage the Soul Patch, despite the hero isn't taking any damage.
If a berry with 2 attack or less attacks a Kangaroo Rider with a Sergeant Strongberry on the field, Sergeant Strongberry will attack the Kangaroo Rider after it has bounced. Leaving both its idle animation and its card icon in the player's deck. The card background is invisible.
This glitch is a visual glitch that makes zombies or plants darker when played. It can be triggered when you play a plant or zombie quickly as the turn starts.
The All-Star Zombie is shown to have the attribute "Shielded" and the multiple attack attribute star on the Collection menu. It is purely cosmetic and doesn't act differently. This also happens with the Jugger-Nut.
"Permanent trait" glitch
Sometimes, when a fighter with a trait that was given by another card, for example, an Imp gets Deadly or a Deep Sea Gargantuar gets Frenzy is bounced, the card in the player's hand will still have the trait icon on the health or strength. This continues to apply when the card is placed, and it will not go away until the fighter is destroyed. This however is purely an aesthetic glitch and the fighter will behave like usual.
This was fixed in 1.6.27 update.
