Boone/companions keep losing their weapons when i enter and then exit a casino...and all their weapons appear on my inventory...
I tried entering alone, having them wait outside...but they keep losing their stuff
Downloading the 1.01 patch, fixes the problem?

Is it Gomorrah? Because I think a lot of people have noticed (including myself) that companions lose their weapons. It's just a bug, and really no way to avoid it other than sending your companions to wait for you in Lucky 38 and going in by yourself.
