I believe I have fixed one of the big bugs, along with one minor issue...
- The star chart was getting messed up because certain sectors of the galaxy were being generated with more stars than the database could handle. This resulted in issues like not being able to scan planets after returning to your ship. It also may have been responsible for the "invalid" pointer issue that some people encountered (though I have not actually encountered this issue, so we'll see)
- Invisible cave monsters. There was a problem in the code that caused certain aliens to be invisible in some of the cave systems. This should not happen any more.
I do have another, content rich, update coming soon. I would have waited to release this update with that one, but the Star Chart issue will cause problems even in current games if you started the game before this update. If you want to avoid this issue altogether, you will probably want to start a new game. Feel free to continue your existing games if you don't mind the database getting messed up though, it *should* not effect other aspects of the game.
