I haven't specifically seen them die and come back, but a lot of times I am unable to hot them (with ANY weapons), your attacks go right through them. I see there are a few tickets logged, might be related to this issue?

Played on Friday (8 Aug) and Saturday (9 Aug), this is still an issue. You cannot attack zombies indoor, as the melee weapons hit the roof of the building, and not the zombie, forcing you to either shoot, or run outside to fight them - please have a look Devs, thanks :)

Played Friday (8 Aug) and Saturday (9 Aug), still a problem, just to keep you posted - thanks
