I wanted to share this info as it took me much searching and a little luck to come up with this, but in a recent play through the Four Seasons Spring room was bugged and the books said I had already completed the challenge.
What I did was:
Started debug mode
turned on debug text
exited the console and hit + and Y keys
found the door’s tag name
opened the console
ran rs gr_dm
talked to the NPC to have it send me to a location
typed the door tag in chat
confirmed with the npc that I wanted to go to that location
the npc teleported me to the door and opened it.
hopefully someone finds this helpful if they encounter this bug
