There is no such post in the past week, all i found was one where you requested a guy to send you a video, you could actually be helpful instead of just pointing me someplace else, or pin the discussion where you solved this.

Start new game or load existing savegame to change options - those greyed out are and always were saved inside the savegame file so it's pointless to allow changing them being in the main menu, all changes will get overwritten when you load existing savegame (with previously saved settings) or start new game (with defaults)

Thank you.
