Small bugfix patch, hopefully fixes some lighting and CTD issues with Shader off mode + freeze on exit. If you've been having these issues give this patch a shot.

I am working on teaching the AI to expand and build things, it'll be a little while before I release that update as that's the kind of thing that needs balance testing.
