After a pause of more than 2 years, I wanted finish PoE for good before the upcoming sequel. So I installed the game again. Except, I could battle Maerwald again, gain the same ability a second time... and I can loot objects that I looted before when I did the dungeon (like Hand and Key armor). It affects other places in the game as well, not just the keep. The quests are still marked as completed in the journal, but I'm afraid of breaking something permanently and lose more than 100 hours of play... So, what should I do?
