Rollback and hints have started working now that I've restarted the game, but I still genuinely don't see an option for saving the game anywhere, which is worrying me. The quicksave I have seems to be only one, from a while ago, and I can't find any way to click save, though I can see the loading screen and all the empty, waiting slots. The help button doesn't seem to indicate any saving method that I can see.
Hey there! Thanks for the feedback! You can actually also save by exiting the game to Main Menu, but this isn't really properly stated in the game. We wanted the game to save when you directly exit the game too, but there were some problems that we couldn't fix in time for launch. We'll try to do something about the issue in a future patch if we can figure it out.
