I restarted the game after the patch so that I may play it completely by the book (the strat guide). These problems are after installing the patch. And one more thing... (maybe this should go in the suggestions section but it's only a small improvement): I think that those massages which fly over the characters showing how much exp they got or what damage they incurred should stop right there when we pause the game. Instead they just vanish in thin air after moving vertically up. They are quite difficult to read already in front of a drak background.
What I do is to save the game before going through any enterance or jumping down any hole and return to the guide and return to the guide and see if I missed out anything.
