Hi, I think I figured out why people keep losing even though it seems that there is no zombie around. So in development i had this one zombie to test the zombie behavior and whenever i wouldn't use it i placed it a bit under the map, and i think what happened is, that i forget to delete this zombie so that he sometimes comes out of the earth and eats the tree. Im really sorry for that bug. I will make the best out of it though, the zombies name is now steven and he is a stealth zombie which was mutated using mole genes. (cause everyone knows, when its part of the Lore its not bad game design xD)
