So I finally get a chance to play this game, but I'm having problems saving.

I turned off autosave in the difficulty options before I started the game. After playing for a while I decided to save, so I hit F5..nothing happened. I tried remapping the save button to another key, which did nothing. Not really sure what to do here, my game is still running. I downloaded the game yesterday on Steam, so I'm assuming the game is fully updated.

Anyone else encountered this?

Edit: My bad. I thought I had disabled only auto-saves in the difficulty settings. I didn't realise the option disables manual saves too.
