Okay, that's something I need to fix as well, then. It's supposed to back up your progress on completed maps in case the game crashes. But I believe I built that system into the main complex transitions, before branches were even added, so I'll go back and make sure it works on all map transitions.
Thank you!
As soon as I can actually catch up with all the things happening simultaneously right now, we'll have a bug fix release that resolves most everything brought up so far.
