I found a box of 45 while trying to survive hypothermia I opened the ammo and used the paper to craft the fireplace I got my fire going and the made some room in the inventory to go collect wood. I noticed the 45 ammo in a stack of 25 pristine rounds I then went and cut more wood and just barely survived hypothermia as I was collecting my gear off the ground and deciding what to leave behind I noticed my stack of 45 rounds was now 0 in size. I tried moving it, dropping it, logging out but it still stayed as 0 quantity there is no choice to split ammo and I found a derringer and it wont load. I'm really not sure at exact point during this ordeal the quantity changed but I found the ammo right next to the fireplace so the only thing i did after picking up the ammo was craft the fireplace collect wood and get warm. I only have shadowplay set to record past 5 mins and after all the fire nonsense it was long past 5 mins so i didnt get any footage till after the quantity already changed but i did take a screenshot.
