For some reason the house doesn't get restored, even though the brothers started using it, without minding the dead body and broken objects around. I have all the quest updates, including the one before the cave entrance which is supposed to trigger the "restoration" of the house. I also have the unofficial patch which is also said to fix the problem, but the house is still a mess after the quest is finished. Any ideas, what am I doing wrong, is there maybe some mod that corrupts this quest?
