Cap'n

I bought the game this weekend and after playing for a little while I went to save my game. The manual states, to save: 1. Press Esc or Enter to display the In-Game menu. 2. Click Options to display the Options menu. 3. Click World Save But there is no "World Save" option! It just isn't in the list, only Hero Save and Load, then the gameplay and display options!?!?! This is quite infuriating as it meant I had to quit and do everything again later! Can anyone help? I hope someone here can help because Microsoft's "Support" page for the game is appauling - just a list of supported graphics cards and no link to contact them.
