It is, but now AXIO Hexagonal Game #678 is stuck, and appears to have become stuck in the exact same way: the game glitched after I placed the first half of a piece and before I could place the second half.

AXIO Hexagonal Game #677 appears to have crashed. It's stuck on "End Game", where I can't do anything but it's my turn. It said it wasn't able to process my move, when I placed the blue end of a blue/purple tile but before I could place the purple end.
