ok don't nerf kudzu but change it a bit

[poland spring]

For thematic purposes, it might be worthwhile to include some interaction with atrazine.

I guess that could count as a nerf.

This is good and also the idea about not allowing it through welded/locked doors is good.  I don't know what people are talking about with it being easy to contain or whatever but honestly, we already have weedkiller in the game so why not let us use it???  and if I can't crowbar my way through a door fucking plants shouldn't be able to get through either
