Summary	0011636: Fortress layout changes after offloading site
Description	My adventurer was exploring a ruined fortress and found a forgotten beast on one of the lower levels. I went back up the staircase to take a nap before fighting it, and when I got back, not only was the staircase gone, but the layout of that section of the fortress had changed.
Steps To Reproduce	1) Load the save in question https://dffd.bay12games.com/file.php?id=15248 2) Note the up/down staircase just outside the bedroom, head up to the top of the staircase to see the level it descends from (it's a few levels up) 3) Sleep 4) Find yourself outside of the fortress 5) Go back in and find that there's no way down to the level you slept on.
Additional Information	The same thing happens if I fast-travel away from the site rather than sleeping. If I go to sleep in the bugged section, I wake up on the ground on the region tile next to the fortress. Interestingly enough, the lower levels of the fortress are still there (discovered with DFHack's reveal command). They're just inaccessible; there's no stairs down to them and no stairs up from them.
