Hmm, interesting. It always worked on the machines I tested. Definitely let me know if you find anything!
ok so I just tested it again by just buying a torch and using first the Exit to title screen option and starting over with my Character file. When I got back in the game, he didn't have that torch I just bought and still had the 30 coins I had just spent.
So then I decided to buy a spear and use the Exit to Desktop option. When I started again, I still have the spear and no coins! At this point, I decided to "exit to title screen" again and load up my character again and I still have the spear and no coins! So apparently the "Exit to desktop" saves the character initially but the "Exit to Title screen" does not. Hows that for bug hunting?! :D ...I only wish I still had my old items but oh well ;p
Note: I started playing with my character and found a tower level where I entered the first stairwell and then the game crashed. Loaded up my character and I still have my spear but none of my recently earned items...so apparently the items to not survive a crash. I recommend creating an extra "save" and/or "auto save" option to fix this for now. I tried playing again for a bit and went to another tower and ANOTHER stairwell crashed me so there appears to be an issue with the tower stairwells on occasion
Thanks for the bug investigation!
Did you have a companion with you when you entered the staircase? I found a bug yesterday that the game crashes when you have a companion and enter a staircase. I fixed it of course!
EDIT: Ok, just fixed the saving bug. Man, what a dumb mistake haha!
