I was playing on server 4268, it glitched when I was killing zombies.
I was on top of a sand bag attacking downwards. The zombies couldn't hit me, then the glitch started. I no longer could hit the zombies. The axe just went through them without connecting.
A few minutes later, my player started receiving hits from the zombies, however, I was still on top of the sandbags and no zombies were near me
