As the title says pistol magazines are for some reason being forced to the top of inventories. For people like myself who always keep their inventory organised this throws us off quite a bit.
(After further time with this, it appears to be crashing some of our games, we currently do not know why this is the case, but we have found out it is actually primary weapon magazines causing this issue. They are the ones that force to the bottom of the inventory, not pistols to the top. We know it is the primary magazines as it is when these are added to the inventory via ground/vehicle/corpse objects the person in question crashes.)
