As title says the zip contains three world saves (one with a current fortress save, two retired fortress saves)

Upon trying to unretire the fortress on either of the two retired fort saves causes a crash to desktop.

Trying to create an adventurer and spawn in the vicinity (any settlement in what seems like 10 map tiles?) or walking there from outside the "crash range" causes a crash to desktop.

The difference between the two retiredfort saves is I ran DFHack commands stable-temp and clean all to see if my issue was caused via some kind of lag induced crash, but no change.
