P0-B1: Part 1024: Debugging, Improvements

I ran into a few additional issues which were caused by the changes that I made to the loading system (in order to fix the other bug that I found), but I have solved these issues now too.

I have also tested the random world generator, and made some changes and improvements. There is still quite a lot to do here to add realistic and unique worlds, but the system is basically working at the moment.

I will probably spend a little more time on fixing other minor issues with the project, and then decide how to proceed with the dynamic story generator and immersive elements in the next few days.
