Whenever I load a game, I lose the fist weapon (eg. knucklebusters), and the hand-held weapon (my poor, poor katana or chainsaw) that I had when I saved the game. Is this a normal glitch? It's really annoying me- it took me ages to find a katana, and then it just disappeared. The only other glitch that I have experienced is vehicles that are required for missions to start (such as TOYZ vans) do sometimes not appear. Do I have a dodgey UMD? Please help.
