I've had issues with items disappearing from my inventory when I swap items within the inventory. Ex.- I have a can of beans in my pants and a t-shirt in my backpack. If I drag the beans over the shirt and select swap items the beans will move to the shirts spot and the shirt will disappear from my inventory. Another issue is items disappearing from the plate carrier when adding the gun holster. Ex.- I have a plate carrier with pouches filled with items. I added the gun holster and all the items disappeared.
