AstroSynthesis is giving me some troubles. I started having difficulty opening and saving a large sector I was working on, so I decided to work on a more stripped down sector, leaving out some extraneous detail I wasn't likely to ever refer to (out planets, moons around gas giants, whatever). Maybe I don't have enough ram to work in AS with really big sectors. I only have three GB.
SO I started a more stripped down map, but then, after saving a few hours work, I shut down. Today, I opened the sector up, and everything I had edited was deleted from the file.
Any idea what is going on here?
