Yep, same here. Too test it, I drop everything I have (Flashlight, bandage, backpack, painkillers.) and I re-log. So far, every time I come back the stuff is on the ground and I have it all again. Good way to dupe painkillers I guess. I've heard of the "Hit respawn then join a new server" trick but still no dice, would love to hear any other way to fix it, or what causes it.
