I have a glitch that when I play Hardcore(Not sure about Reg, don't want to risk losing my gear on their) I can play for so long, find a safe and secure place to log out, whilst waiting a few minutes just in case I had any zombies staggering about. When I re-log into the same server, I am a fresh spawn again :(
One reason as to why this bug annoys me is that, I had a fully geared out AK101 with a LOT of ammo/mags. I then logged out with my squad to take a break, we had returned to the same server and I noticed that I was a fresh spawn. I ignored what happened, to get fully geared out again on that server. We ended up coming across a heli crash, and I found an M4A1. After playing for awhile, getting geared up & hunting players, we decided to take another break and return back in a few minutes. As earlier, I became a fresh spawn. I had logged out both times, in safe and secure locations - even waiting 1-2 minutes to see if any zombies were staggering about near the location.
