first bug: weapons attack door instead of zombies when zombies are close to it. and if you use taser on door zombie are forced to attack doors instead of yourself.
second bug: survivor can move even when you put them on hold position.
"improved suvivor's AI"
this is actually a bad improvement of survivor now you make survivors run into zombies
it is better to make survivors run little back when getting attacked instead of running to a position further position.
