i got an infinite loading screen after collecting the 5th clue.
as soon as bellegar was about half way through his last line of speech (something about a womens womb and tomb etc.) the screen faded out and was replaced with the loading screen and there was the sound of wind rushing etc but the game never loaded. even after waiting 5 minutes or more.
had to reload the autosave, thankful there was one at the fight and that it didnt crash the game, and skip through the text quickly when bellgar spoke after defeating his minions.
