Were you not even able to start the battle at all?
Because I’ve checked your account linked in your forum profile and I can see AB battles successfully played with no errors, battles started also submitted the results correctly to the game server. This basically means your Xbox went out of sync before the fact you tried to start a battle even got sent to the game server.
Or does the error happen in one of these places instead:
- When you open the Adventure Board
- When you select the Adventure
- When you select the battle
- when you select the “to battle” button to start the battle
Any additional details you could provide about when and where the error message happened exactly would be great, thank you!
