Every time I have accepted an undo when playing with the Nocturne cards, the display gets messed up. Visually, it looks like it's my turn, but my opponent is still playing as normal.
EDIT: I have attached a screenshot.
I assume you have the Kingdom set to 'moving' in the options. This has been reported by some other player and I have confirmed it myself. I don't think it has anything to do with the Nocturne cards themselves, just that the update for Nocturne changed something that created this error.
