New threat.

Thanks for the information! When I have time, I'll thoroughly clean up the map; maybe it will help with the saves. Where exactly do you need hints? I also don't understand why the game crashes when saving. I only experienced this after a new game, the saves themselves are fine. Many portals won't open on their own; you need to find a way to activate them. Hint: you don't need to go very far to find the solution.
