Sanctuary - "Defeat and Victory" [Campaign 4 - Mission 2]

I completed the mission, but I didn't complete the side quest to banish the wolves, and I also don't have the fortress.

Try creating a second hero with a perk from the dynasty (hiring a second hero without paying) and within two days, have him run to that fortress. If it appears, then everything is fine; if not, restart the game. In reality, this is a bug in this map.
I completed this quest on the 6th day, after gathering all the resources in the castle's area of influence and building structures for regular creatures.
P.S. I spent two hours studying this bug, saving and loading to see when the fortress disappears, but I still couldn't figure out when the script for the fortress glitches...

Can you tell me where to find the body of the missing Pearl Priestess in the Kirin-Snow Maidens quest? If possible, please provide an approximate location.
