Prior to installing the patch my game probably froze twice and didn't have any other problem. Now I have this really annoying game breaking problem,

i am in Primm and just repaired ED-E. Now whenever I select the sniper rifle using the Hotkey, it disappears and I can't use the hotkey to even equip other weapons that I had on it. The game won't even let me re-equip the weapons as it doesn't register them.

Once this happens and I try and load a game, it instantly freezes. I don't know what the deal is because the game was working fine before this. Anyway please fix this issue as it isn't a random freeze, it happens after using the hotkey.
