Game froze + weird fragmented save?

[EFox2413]

Okay so i was playing on my berserker and i killed the sand wurm queen and ate her heart. When i exited the game froze and wouldn't respond (I was also tabbing in and out of other programs, it wasn't on full screen though). I ended up having to end the process. The strange thing is that when i reloaded from my last save (I was in the maze level 4 just like i was supposed to be) I went down the maze killed the minotaur again exited that level and then went on to do the sand wurm one. However in the sand wurm's lair the map from one stairs to the other was already explored like i had been there before. Although there was no way i could have been there at the time because i was already 4 levels deep in the maze. When i got to the last level of the lair there was no sand queen to kill and the quest can not be completed. I think this has something to do with unlocking a new class as well perhaps?

Zones are saved in different files for efficiency so it's possible for a zone to be "newer" than the savefile in case of a crash.
I have plans to fix this
