ok don't nerf kudzu but change it a bit

[Roomba]

I agree with the thing about it being blocked by welded or bolted doors, but the issue here is that the AI can stop the kudzu from spreading entirely once it finds it with very little effort.

On the flipside, maybe the AI should be allowed to do something about it, since right now without a borg, all the AI can do is yell for random people to do something about it, which has roughly the same success rate as yelling out the window for random passers-by to mow your lawn.
