I encountered an issue where there wasn't enough cards at the end of to finish the last pile. I ended with 10 face up and 9 face down, but I need 11 of one of those
Oh gosh unless this isn't a bug and you need to strategically bias which cards you use.
That's the intention, but there *is* also a bug that caused there to be an uneven number of face/back cards. Sorry about that.
