I've had desync before but it's taken on a new level in the current EXP 0.61 build. I'll be running away from zombies only to have the zombies attack a space I used to be in and continue to hit me, from my screen I can see them attacking the air whilst I loose health, blood and eventually die.

It's happened twice in Elektro on a medium pop server. Both times I've been a fairly new spawn with limited gear.
