I play on the ps5 and this happend in my solo world.
When i tried to put my experimental ag4 into my storage my exp ag4, exp pump shotgun, thier respective ammo types in my inventory, 1 remote explosive and adren shots vanished. My weight went from 74kg’s to 42kg’s but my storage only went from 338kg’s to 342kg’s
I was able to recreat it one more time when i took a spare exp ag4 from my storage station and when i put it back it also vanished but after that i was not able to recreate it
