Start a new game. When you get to the map screen, click at least once (and hope that the gui doesn't die more than twice)(It really likes to die on your second click)(If you spam the button immediately it sometimes goes through), and then choose whichever map you would like.
Depending on how many times you clicked the change map button, you will get extra Arks at the start of the game. They are, however, waaaaaaaaaay bugged out and they are also uncontrollable. Also, if you have too many then the Ark that you can control wont produce any ships. Which pretty much means GG.
There are lots of other fun, wacky things about it, so have fun before they fix it!
