I7 6700k 1080 etc etc
Repro, In this case toss an Exp Kpist tied to ~400 FMJ 9mm ammo into the box, and later picking it up with another char, in this case a ‘mule’ makes it take the weapon (whose attachements isn’t visible in the box, while they still are fully removable under the attachments tab, while not even there visible as tied to a weapon, so easy to dismanlte the wrong stuff) Results in it dragging all the stored >4.5k 9 mm FMJ ammo from the storage as an ‘attachment’, resulting in quite some weight added, even as he were already carrying some 9 mm FMJ ammo.
Game breaking? No!
Risk of taking weapons apart by mistake and give pieces away, or recycling them by mistake? High!
Going OT from original bug-report subject and into feedback territory Quite high.
Suggested solution: Let us ‘lock down’ weapons as a ‘unit’ when equipped and stay that way in storage. Hide their attachments in the box, and or make it clear that they are tied to a specific weapon. Hidden they could show the way they show on equipped weapons, on the ‘attachment line on the weapon’, instead of visible as ‘free’ in the spare junk attachment tab in the box
Boring video showing it suddenly tied to all ammo:
