I assume that you are playing on a Mac? Some Mac users have mentioned this problem to me and it is apparently due to a permissions issue on the user’s end. Mac doesn’t allow certain applications to overwrite files so it stops saves from being made or options adjusted.Unfortunately, I can’t tell you how to troubleshoot this problem exactly, since I do not own a Mac myself. I’ve read that there are settings that you can adjust to get the game to perform properly. Sorry for the inconvenience.
