A few folks have had problems with "floating" inventory items...no patch yet that I've heard about. I'd recommend a couple of things. Click on menu and restart the level. If it does not fix the problem, delete the game and redownload. BFG has confirmed you will not lose game progress except for the unfinished segment. A couple people said this fixed their problem. If it does not, go to the My Account tab and contact BFG Support. The folks there are terrific and will help you resolve the problem.
BFG HOSTS -- any word on a patch for this issue?
