So I had just moved from Floor 3 to Floor 4 and the floor loaded without any tiles - I could see doors and items but the floors and walls were utterly black. Thinking it had loaded incorrectly, I went back up the stair to Floor 3, which loaded fine (as it had done previously). I then tried to head down the same stairs again to floor 4. The game hung up and I had to force close it. Upon reloading the game and attempting to reload my save, the game hangs again. Strangely enough, the image for the autosave is from Floor 2, which obviously is nowhere near where I actually was. Sadly, I do not have any other saves for this character. Also, when I exited the game, Steam applied another update to it. Note that I already had Wizardlands installed, so I have no idea what this update was about. I have attempted the fix floating around the forums and (while it did restore an old save created prior to Wizardlands) it did not fix this save (which has been created and played entirely in Wizardlands). EDIT: I do not have any mods installed. Cheers!
This may be similar to something I just noticed - while my /save/ appears to have been where I left it, the /autosave/ appears 'above' the save in the list of saves, but displays the image from when I last saved and logged out before the most recent time. EDIT: And when I just 'save and quit', the Autosave was /completely gone/.
