- When you agree to escort Wulfram to Cyseal, go to Abandoned Basement after that and quick save there, Wulfram doesn't go to town after load(dialogue isn't available anymore, he just stands in building and tells you pharse which appears when you escort him). - You can kill both guards in Barracks prison, and everyone outside Prison stays friendly. Not sure if it's OK.
One more(maybe mentioned by someone already): when in combat you select skill and then select another without cancelling first selection, will-be-used AP(red AP dots) count is incorrect.
