I tried posting this in the bug forum, but it's not being posted. The zombies in my game do not walk or crawl around. They are frozen with only their upper body sticking out of the ground. When I get close enough to aggro, they quickly pop out of the ground and chase me, but once they get up to me the get sucked back into the ground. They attack me from the ground making them hard to kill. Been doing this for the past week over 1.5.6 and 1.5.7.
