I'm pretty sure this would have already been addressed.  However I couldn't find the post....................
Is there a file/folder I can obliterate out of existance that holds my custom ships?  The damn game crashes WAAAAAY too many times (yes, I've gotten used to the damn thing crashing) whenever I modify a ship.  ESPECIALLY if I "overwrite" an existing one I made.  Is there a way to take care of this?
