Due to the illegal move (gocubbies exposing his king after his loss), the game is rewound to the moment right after the duel was decided.
So gocubbies' actions (I'm posting it because I told him to delete it, wrongly):
d2 -> c4
d4 x d5 (2-0 victory for The Mormegil)
? ? ? b1 -> b3
Gocubbies has 1 more action left.
Edit: last move is b1 -> b3
The game can go on; I hope everything is cleared up now.
Edit2: fix.
