Hey guys!

So I have this problem where a survivor in an adjacent building keeps firing his rifle. Hundreds of times. Non. Stop. He's been doing this for the last 18 hours, just shooting at the wall of his safehouse. When I tried to look what's up, the ♥♥♥♥♥♥ shot me in the neck and almost killed me.

Sooo... yeah, what's up with that? Is this a bug?
