I purchased the game and the expansion through Steam. I'm running on a 64-bit OS X Lion install (10.7.2). I started this game today, have saved a number of times. However, after going down to the second floor and then back up to the first (to sell stuff) and saving, exiting, loading, I now crash every time I try to load. The savefile has been uploaded below. It should have an md5 of a8c36c0d5a401311fe72a4e517621f35 (just to make sure it didn't get corrupted)
I have an exactly same problem on Linux x64. Some save files included. They all crash when trying to load. Character LLyrana was created in 1.0.8 and Alliran in 1.0.9
