Fixed the issue of the mouse not working due to the mouse sensitivity being reset to 0, causing the 'looking at lights' section when you start the game to not work properly.
The settings will no longer get randomly reset either.
I don't know what was causing this, the person responsible for the Save plug-in was not very helpful. I'm now saving settings in a different way that doesn't involve that plug-in. so hopefully there won't be these issues.
