If I am missing a constellation, please neomail me.
If the newest constellations won't load, it's because you have an old version of the mapper cached. This server does not like to update the files, so you will probably need to clear you cache and reload. Make sure the last updated timestamp is the most recent version before you think the program doesn't work!
