I just lost a run to a peculiar bug. When a zombie try to climb over a fence, they will fall over. So I walk up to her with the intention of smashing her with my crowbar. However as my crowbar connects with her, she instantly stands up like she hadn't fallen at all. And her companion that came with her did the same thing when my crowbar accidentally hit her as well. So I suddenly had two zombies instantly stand up and bite me. I don't know if it will happen with other weapons, I have only tried with a crowbar. I love this game, so I made an account to submit this bug, keep up the great work!
