Well, I've been messing around with the trading mode for a while.. looking for certain ships (The larger carrier used by the fairy empire, I haven't been able to find that. Not talking about the modular one) and ended up figuring out how to modify the save file to force stuff... found this absolutely dashing ship.

It's called the moon battleship in the save file, it's clearly unfinished.. I could force it to be fairly workable if I was able to extract the BIG file, though I've tried a few times.. it only outputs a single file that has no bytes. I'm guessing it's a locale issue?
