Glitches

F uck I hate this game now. It was fun all the way up to the Venetosaur Level, where I killed the smalls ones, and then according to many guides, a big one is supposed to show up. The thing is, my game doesn't want to load him up, so now because of Ubisoft's failure to do proper bug testing, I might have to start the game over from scratch. Anybody have any other glitch encounters?

EDIT, I restarted my system and that made the big dino showup... but now it seems I have no voice overs, which I hope won't be that big of a deal, even though this game so far had great voice acting, by the stars themselves. Only thing I've noticed bad so far is that I don't know how much ammo I have left.
