Hey, maybe you can get something out of what happened to me today on Northeast 0-3 Exp server, happened at around 4:50 - 5:00 pm US eastern time

Bullets were not registering on zombies on either of my weapons, M4 and AKM. Then my M4 vanished out of my hands.

I retraced my steps and found it where I had dropped it in a tree a little ways back. I had dropped it to eat. I ate 1 item, then it would not let me eat my tuna, or my sardines. So I just thought it was a bug with an item in my hands, so I just put the food back in my bag. I then picked up my M4 and started to move. This is when I started shooting at zombies at the north side of NWAF. No hits with the M4, and no zombie aggro, its like they didnt hear it. Switched to my AKM, same thing, no hits, no aggro. So I headed east into the woods, thats when my M4 vanished from my hands. I went all the way back to the bush I dropped it in when it wouldnt let me eat, and there it was still laying on the ground.

Then I noticed a chopper crash that seemed to just spawn in, but there was no chopper and no loot, only smoke. It seemed like the smoke was coming out of a tree. Like the game though the tree was the chopper. But I was thinking, maybe the chopper crashes are tied to this bullet reg bug for some reason?

Also I just noticed, my screenshot on Steam shows it as being night time but it was clearly day time as I was playing.
I will upload the screenshot of the chopper spawn, but like I said it is very dark, even tho in my game while I was playing it was day time.
