Tried out the new Mac demo v2.0.5, and seemed to have issues with the save functions.
When starting game, I cannot start with the first save slot, and can start using the second save slot.
When I try to save in-game, there is an error message that save has issue.
When I try to exit the game, it prompt that I've not save for a long time and ask me to save. When I try to save the save dialog disappears but the game just don't proceed. I'm forced to quit without saving.
