Don't know if this is wanted but I wanted to make a thread containing most bugs so simplify going through everything. I hope these get fixed in an update or something because it really is a wonderful game and I am quite enjoying it.
-Random Crashes when walking around.
-Game crashes when I've killed all the Orcs in the SE corner and start battling the Orc boss (Balzar or something). I've not got a mission to kill him so maybe that's why.
-Game crashes when I enter the Church. Cutscene starts with both inside characters spinning like mad and then the game crashes.
-Game slows down a lot when its dark outside and light sources are active. Inside the castle and one of the inns there were many lightsources and I was walking very slowly.
-Using any of the statuettes crashes the game.
-Characters occasionally spin.
I will update if I solve anything or have something to add. Hope the game gets fixed up enough for me to play it through as I would hate not being able to play through this game as it really is good.

Anyone feel free to add to the list if you got something.

Great idea.

Games will sometimes fail to save to the harddrive (a temp save is made). The next save attempt will usually work.
I'm pretty sure this one was fixed by disabling my virus checker (Avast), but I've moved on from the area it occurred in (in the first underground area), so it's a little hard to tell. Worth looking into either way, as it has happened to a few people.

*POTENTIAL SPOILER*
I'm experiencing a bug when I return to that starting town to recruit head healer guy to the Council of Seven. The hag lady from the Duke's castle comes out and starts spinning and the game crashes. :(
*END SPOILER*

bug report (edited 11/14): hitting LIZARD MAGES in sewers causes crash to desktop. if i do it real slow i can sometimes get away with it but there is a very high risk of crashes each time i do so.
okay, just tried again. no matter what i do killing lizard mages causes the game to crash.
stuff, I'm editing this earlier post in response to you because I want this list to be a resource for larian and not fill it up with questions and crap. so in the interest of saving space i'm going to reply this way.... unfortunately I have neither poison weapon nor freeze, I am trying to play it the hard way with a wizard and i can kill all those guys just fine except that the game crashes! but if i absolutely have to i'll learn the freeze skill and kill him that way. i have two skill points floating anyway...

Same problem for me but I was able to clear the sewer mages using left click poison weapon and right click level 2 freeze skill. Might work for you as well??

The game crashes in Arakand (wasps & bees) right after the conversation with the Wasp...
...and I also have the church and Orc leader crashes....
New one: can't "activate" (left clicking) on anything in warriors guild. So i can't go in the catacombs, pickup stuff, etc...

update on lizard mage bug:
it seems that DD's video engine is really sensitive. anytime there's too much going on it may crash. so my problem was that I was using skeletal wall to hold off guys, then use hellspikes. but too much stuff going on, so it would crash. when i tried the sweres again, without using skel wall, and use meteor to kill the mage, it worked just fine.
i tested out the church bug though. oh yeah, it's a total CTD. same here

This is a simple non crashing bug:
In the mining shaft that leads to the ork camp, the corridor next to the upper eastern exit has a bug where when you stand on the upper part of the floor, the floor will loose all lightning properties standing out grossly.

A minor bug . . when changing skills during a battle. . . if you right click instead of left click the skill icon . . . the command icons collapse into a thin blue and red line across the bottom of the screen. ( It usually occurs when I right click the poison weapon skill ).
No key ( that I know of ) to hide or show the command icons, to fix it I just reload . . . not a game ending bug. I know . . . I could pause to change skill but where is the fun in that?? =^ )

That is by design, it's called "the most minimalistic UI modus ever". Blue = mana, red = HP, yellow = stamina. To go back to the full UI, right click the thin bars again.

Thank you, the one thing I didn't try !!! I must have missed that feature in the manual, was going to suggest what was already a feature.
Edit: I like it. . . . =^ )

yes when i first saw that my heart sank and i thought i ran into a video glitch, but then i realized that it wasn't just a random bunch of colors. then i right clicked it and i really appreciated how there is a way to minmize the plates!
sometimes you really want to see more! (esp if you are playing at 800x600, which seems to be the most stable resolution for me)
