Once you are on Day 10 at the least, you can finish all of the quest. You don't have to finish the quest on the same day! Are you saying that you still have trouble with the day? If you choose to go to bed without a bedmate, it still just reverts to the shrine without rolling over the day?b I've tried replicating playing the quest, but the day rolls over to the next one as soon as I go to sleep alone. Is this still a problem?
I think I know what the problem is with the skill, though - I'll streamline it and add a fix in 30 mins!
