Random New World in Conquest of Paradise save reverts back to standard North America

I tried searching for an answer but I didn't find anything.
With the new expansion, my friend and I are doing a playthrough as native Americans in a randomized new world, but last time we loaded up our save game, everything was reverted back to " standard North America ". I've tried the obvious things like reloading the game, and making sure the checkbox is marked, any help ?
