Summarize your bug Bots can sometimes completely stop working. They can't move and won't shoot or use abilities. I have encountered this once with the AI Corn in the video. This Corn was invincible. The second time I encountered it (AI Acorn), the bot could take damage (not from hits with the primary but Super Stink Cloud) but didn't respawn after being vanquished.
Steps: How can we find the bug ourselves? This bug rarely occurs and I don't think any steps can be taken to tigger it.

What upgrades had you equipped with this character? /
How often does the bug occur? Rarely (0% - 9%)

@benn1nat0r I find this several times, sometimes the AIs can jump and move slightly and not receive damage from all sources, it could be that they have died and randomly the error has come out although if they still receive damage, it could be an error in their programming

I have also seen it happen a few more times. I have footage of it happening to a bot Acorn which I will upload here after I found it on my HDD.

SO far I have only seen it happen to plants.
