I have a camo-covered tent in the woods near Green Mountain. I placed a Blaze and a Vaiga in there while I managed my inventory, and when I went to remove the guns from the tent, I was unable to. The options for Equip, Place in Hands, Move to Inventory and Drop were all there, and none of them worked. (I made sure I had enough room in my personal inventory before I attempted to move the guns there & I had an empty slot to equip the guns).

I was able to move all other items, including ammo, clips, shovel, canteen, food, etc, but no matter what I did, the guns did not respond to any command. I even logged out and then logged back in, and still I was unable to interact with the guns.
