There were 2 zombies, one of them was stuck in the pond, the other one came from the city and he just jumped inside to the pond and he didn't even need to swim, he just walked under water and came near to me. I axed the zombie and then I suddenly started sinking inside the water (imagine we're in a swamp and the swamp is constantly pulling me inside) however my position keeps getting reset, to top and then I start going down, this loop is infinite and animation changing did not work.
