first off zombies just walk through closed doors and solid fences. another problem my friend and i have encountered is we logged of of a server having not being killed and got back on to find his character had reset for no reason that we could think of. that specific incident with the character reset happened in first person mode if that helps.

for the first issue just be in a house with a closed door when a zombie spots you he will come through the door, or when your being chased by a zombie and vault a fence and the zombie will go straight through it. the second issue all we did was log off and hi stuff was gone.
