Fortunately, that appears to work aswell. I'll have to go over half the work I had already done, though. Oh wellI even replaced all the affected quests with an earlier back up from before the "erro" appeared and it still shows. I'll try replacing them with the original English files just to check if it's not corrupted beyond all repair, and if I can edit them again from there, but if that fails, I'm officially out of ideas other than a fresh installation.
