Loving the Xbox One version of Pit people!
I was playing it co-op, and have encountered a game crashing bug twice in the same place now.
After the 3rd battle (where you capture the cupcake), I return to town, and the item screen pops up (where you can trade items). After hitting A on this screen, the game immediately crashes.
This has happened twice now at the same spot, and unfortunately there's no way to save before that (meaning I have to do two battles to rediscover this bug).
Any word on when it will be fixed?
