I loaded the game to see how the map was progressing and found that some of the star colors were changed. I reloaded the editor only to find that when I tried to select one of the affected stars I got the same access viloation as I indicated above.
Now whats odd is I quit out of the editor, then downloaded your latest version and ran it again. This time the stars are back to the original color I set both in game and in the editor. I don't get the access viloation now for either the resources nor the stars as previously mentioned. But I am not so sure it was your latest version that may have fixed it.
What I suspect is when minor races happen to inhabit a planet that is in a star system that is green, purple, orange or any color other than yellow it changes the color to yellow. Then when you try accessing the editor after closing the game, you get that access violation for those stars until you quit out of and reload the editor. Since in the original game only yellow stars have habitible planets, this may be the problem. (Added in..I just want to confirm this is exactly what is happening, I just run another test on it and minor race placement is changing star color to yellow.)
Here is an addressing issue I found. My starting square is 4, 13 and although square 5, 13 is to the right of 4, 13 in the editor, items placed in it are placed above it in the game, and items placed in 4, 12 get put into the square to the right of my starting square. These are the only squares so far that seems to have a bit of an addressing problem. 4, 12 and 5, 13 are reversed.
