I have been having this problem too. Before recent updates I was able to kill zombies with one or two hits with the fire axe (and other weapons/fists), but now I am unable to land any hits on any zombies. I just died trying to kill a single zombie with the fire axe; I had full "healthy" stats (hydrated, energized, healthy) and I couldn't knock the zombie down once. After five minutes of continuous axe-swinging the zombie owned me. I can stand as close to the zombies as possible and not be able to do any damage to them.

I agree it's really annoying that zombies can attack players from around 10 feet away. They can also attack players through floors/ceilings. I've been taking a lot of damage from zombies that are below/above me in buildings. Because I can't see them, I don't realize what's going on.

Additionally, the zombie hitbox when using axes (and most other weapons?) is seriously broken. It used to be possible to hit zombies, but now it seems like it is a very small chance that you can actually land a hit on zombies.

These two bugs make the game experience really shitty when you're on full health and you get owned by an immortal zombie (who you can't land a single hit on) that can attack you from 10 feet away.

I get this bug very frequently. (Reproducibility = 100% of the time- this bug occurs at least once or more every time I play the game.) The animations for consumable items will not play and then the options to drink, eat, and bandage disappear. It also occurs when using objects that are not inside bags. The only way to fix is by exiting the server and logging back in. This can be a game-breaking bug when you are bleeding or close to death. I am also playing on Windows 8.1 .
