ok, I found new bug ;P
On Kilian's route - when Albert gets back to the castle after Kilian attacked him, when they talk and there is a choice "I didn't realise that it was that bad..." - when choosing it goes stright to the to the ending with 'Heart of Poison' that is dedicated ending for the other choice.
Damnation...^^ - and here I was hoping to find more about Kilian ;PPP (no worries, it's kind of fun to be first to find bugs^^)
