I have since yesterday been unable to do any manual saves.
At first I thought it was because there was an update and someone had the idea that you can't save before an update, which if were to be true would be stupid beyond words.
But even after the update and today I have been unable to do a manual save.
When I go into the menu and click on "Create new Save" it gives me a sound as if to say I can't save right now for whatever reason, the problem is that I can't save anywhere.
I don't know what triggered it as I had no problems before.
