Played the same or more hours, but the last 1.5 hours(approx) I was having serious issues. Mentioned these issue in game, I'll describe them more here:
It started at the Warehouses/Civilian Hangars at the end of Balota airfield. I arrived there with Z in tow, killed 1 in a hangar, then after looting proceeded on. Left the hangar and there were 3 Z doing their standard walkabout. I only had a Hatchet so a choose 1 that was alone enough that I could attack, then escape from the other 2 if need be. I Ran up to attack, it dies, the other 2 do nothing. I run up to the next, repeat results, then went and killed last one. All 3 times, even the victim didn't even aggro, they just carried on shuffling.
After that I head east then north, looting here and there, rarely seeing a Z, although I should have seen many as I went through a few small towns and even the outskirts of Cherno, Sprinting the whole time.
Part way through I then noticed my Debug monitor was gone. Seemed strange, thought maynbe I hit a key by mistake or something, but am sure there isn't one.
Finally, the biggest thing to happen, and the one I mentioned the most ingame(I mentioned something else earlier ingame, the Z not Aggroing situation IIRC), I was nearing a Barn between Kozlovka and Drozhino when all of a sudden the screen flickered and I was back in the Warehouse/Civilian Hangar at Balota airfield again. That was the better part of an hour travel erased, as far as I know all loot acquired was still in my Inventory.
Other observations:
1) Chat worked fine, no delays
2) Whenever someone used VOIP, usually incorrectly in Sidechat, their names never appeared. Perhaps this is a Server setting?
3) When I first TP'd back to Balota, the floor of the Warehouse/Hangar had no texture. Probably just a delay on loading texture on my end.
Not sure if I was Desynced or Hacked(vaguely recall talk at DayZ forums about a Hack that takes over other Players, not really what happened to me). Maybe there's a glitch in that building and I fell through the world or something...but now I'm really reaching.
Perhaps the server Logs have some data related to it? Anyways, I am enjoying the Server a lot and will certainly be back. Hopefully this was a 1 time event.
