Nether bosses don't spawn for me due to shrine advancement portal bug

I think my save file is partially broken.
During the time when the portal in realms spawned a teleportation shrine instead of an exit portal, I took the shrine on floor 1324 to nether floor 1325 and the nether boss did not spawn.
Even after the bug was fixed when I go back to floor 1325 the nether boss area doesn’t display nor future nether bosses on floor 1330. All that displays is a normal nether realm.

Yeah, I think that bug could have broken the file a bit. If you want to attach your save file here or e-mail it to me (zack@thylacinestudios.com) I can fix it for you!
