I started using PAS yesterday and I enjoyed it alot. I made a nice bridge with a nice house and was pretty happy with the result. I saved, and exited. When I decided to edit some more, I opened up and tried to load my save. Didn't work.
I started making another map and I've spent most of the day making it. I decided not to exit from fear of not being able to reload it, but the worst possible thing happened: the client crashed!
Now, I REALLY do not want to start over again, so is there any fix to this issue?
I'm going to add 2 pictures as well, to describe it better.
