@Ch3rub: Is there a thread about the bug with Loredo's house? Do you know whether the bug only occurs if you go to the house as part of a story sequence (with cutscenes, dialogue etc.), or if it will even occur if you just enter the house later? Do you know if you and the other guys having this problem have the same soundcard?
About the sound distortion bug: By becoming very slow, do you mean a drop in fps (stuttering), or does everything move like in slow-motion? Did you try reinstalling 1.1 from scratch?
I don't know if there is separate thread for Loredo's House issue, couldn't find one.
Happens with different sound cards. I have Asus Xonar, my friend integrated Realtek, third person's audio card is unknown to me. I was at Loredo's House only as a part the story, my choices did not really give me a chance to to there more than once.
As for distorted sound issue - yes, it looks like drop in FPS combined with sound distorted. Very weird and quite hard to describe tbh. This is easy fixed with going to menu and back to game.
Haven't tried 1.1 again yet. I've had a reply from tech support to try 1.2 which I will do when I come back from holidays.
