I've attached my savegame right before Bagud's fight. All remaining quests in my quest log are buggy.

So, any news on the bugs in the quests? Is there an solution, or fix for it? Don't really want to play on if the quests keeps breaking.

The Seven Forms of Haas broken quest save.

Is these problems getting fixed at all or are we just screwed? :P

Well, most likely you'll have to restart the game, as these problems are related with old bugged version of the game. The current steam version doesn't have such problems, but old saves may not work properly with it. In fact there is almost zero chance that old saves can be fixed due to technical difficulties.
I'm really sorry that this happen, but in this situation starting a new game on the latest version will be the best solution to avoid bugged quests.

So we are screwed. :evil:

I am disappointed that after finishing the game without issue, there were several "patches" released plus a save game fixer to allow us to continue playing with our old saves. We are now being told that our fixed saves are actually not fixed but totally screwed and we have to start again.

Yeah, I'm pissed as well, this will be the third time I had to start over because of a new patch, freaking annoying. Going to shelf this game a while, cant be *** with it now.
