I've had my own personal server for a while and there are A LOT of zombies on the map as i've edited my files and pretty much whenever I meet a zombie its a death sentence because of the disease update it gives you a disease (not sure which) and I don't know how to recover from it, it gives you much more thirst and can easily kill you as drinking from anything except cans is a gamble now not even purification stuff will NOT help (that's a real big glitch) no matter what when drinking from a well after getting increased thirst which I do not know how to recover from its a gamble weather my character will end up dying.
