I have run into a few bugs myself, and they're driving me nuts. P:T is a great game, except for the constant threat of the game suddenly freezing or quitting or whatever. 
Here are all the bugs I've run into so far:
1) Morte can't use his Taunt Ability...Left-click on him, right-click to bring up the action window, left-click on Select Special Ability, left-click on Taunt, right click to get out of the window, and the taunt symbols start to appear over him, and then the game hangs and I have to restart my computer.
2) Fall-From-Grace can't level up; whenever I try, the game crashes with an error message.
3) I also have an error message when I complete the Rauk quest...I give him the rings, the mages start to cast the spell, the Killer Lim-Lim of Doom (
) appears and manages to kill one of the mages, and then the game crashes with an error message (but it's different from Grace's error).
4) If I stay too long in the Mage/Priest spell books, the game hangs and I have to restart.
5) And lastly, and most importantly, in the Modron Maze, the Evil Wizard Construct casts the Mechanus Cannon spell, I get a cut scene of a huge cannon blasting a torrent of energy, then I return to my "body" still surrounded by the High-Threat Constructs and the Evil Wizard, and although we all are able to shift positions (so the game hasn't hanged in the sense of 'no motion whatsoever'), nobody can move, attack, cast spells, talk, etc. The bottom portion of the screen (that shows character portraits, time and options) is gone, and I have no right click ability. I still have sound, but no control.
If anybody has any suggestions on how I can fix some or all of these bugs, I would really appreciate it.
