So i put any items ( mostly every item in rust for example weapon attachment ) in any crates, it works how better loot supposed to work, but the problem comes when i looted the first box, i can get the attachment in my inventory, but when i looted the other box and tried to stack it, the items just gone, it backs to only 1 item in my inventory. But i can get the loot if i seperate the stacking, like 1 each. Please help me to fix this, sorry for bad english.

but i tried make the attachment by myself, and it can stack up to my stack size using stacksizecontroller. But cant stack if i looted from the box.
