Had more of the same problem found a carbine repeater in an abandoned backpack, managed to equip it leaft the area and then realized it had disappeared I am sure I did not drop it by mistake. Considering the same thing happened the first time I experienced the problem. I also had trouble looting my boady from the previous survivor i played, although I did manage to retrieve some items but not all notably a screw driver. Not sure who will read this but thanks anyway hope there is a fix
