After grabbing a longhorn (oddly with a crossbow holosight) I wanted to swap it in my hands with my loaded B95 so I clicked and dragged it out of my hands to my back pack where it showed in the backpack for 1 mili second then disappeared but there I was still holding in myhands but without the longhorn portrait in my hands vicinity and just the holosight in the equipped slots as if the longhorn portrait was there.I ended up pressing 1 in my hotkeys to swap with the b95 and that did the trick but with the lonhorn completely gone.
