So I was in for a number of ugly surprises when Wyren went back to the Alchemy Hut to check on her merchant today....
The Good News:
1) Wyren still owns the property (as I confirmed when I walked Corella and Zelis through the front door).
2) All of the placeables inside are still where they should be.
3) The merchant sign outside the front door hasn't changed.
4) Neither have the front door's title and description.
The Bad News:
1) Both Wyren and Corella (who have both been inside the Alchemy Hut before) got "New Area" XP on entering. That's not a good sign.
2) Wyren's merchant (normally standing in the middle of that magic pattern in the picture there) is gone, and all of his merchandise and Gold are gone with him.
3) Both of the doors to the side rooms are back to their defaults (Locked, Lock DC 25, Hit Points 15, Hardness 5), even though Wyren had spent quite a bit of money improving on the doors, particularly for the storage room (which had its Lock DC up to 40, its Hardness up to 15 and I forget what the Hit Points were). Wyren kept both interior doors locked.
4) Both of the chests in the storage room were empty. Whether this was because of the house bug or because of some opportunistic soul who took advantage of the now-weakened doors and looted the storage room, I do not know. I had quite a few Letter Cylinders in there too.
Wyren was all paid up on her property taxes for the next year. She doesn't have her merchant's deed in inventory, so her merchant apparently hasn't been recalled. I haven't changed any text or placeables on or inside the property (and won't do that until I can get this fixed, lest I knock some random 1 or 0 out of place and lose the merchant and his stuff forever).
So what happened, what may have caused it, how many people have had this happen to their shops before, and is it reversible? :s
