This is going to sound REAL weird, but updating to the latest version may have fixed quest 7. Before, I didn't see the ghost that started the quest, just the "demon at the end of the quest" after resting once without a bedmate. Now, after a few days the ghost showed up, and I'm going "uh...this didn't show up before, now I understand what Paper Waifu was talking about"
Given that quest 7 was bugged before, after seeing the ghost, do I have to visit someone next to get the details needed to find the demon? I think quest 7 was bugged before (didn't actually see the ghost before this) so not sure what I need to do! I saw the ghost at the end of day 5 and 10, but afterwards it doesn't seem to do anything (day 30 and she hasn't shown up again).
