You have no room for that...
A couple days ago I crashed and when I logged back in I had one cloth scrap on my back. I couldn't drop the cloth and when I tried to pick up more it said "You have no room for that." I relogged and the cloth was gone, but now I can't put anything on my back. It keeps saying "You have no room for that." It's not showing anything on my back and I can't pick up anything that goes on your back. I can still scavenge and pick up anything that goes into your pack, but not on your back.
