I had 1 loss and 5 wins. I'm winning and my opponent has no chance. I'm making my final move as he leaves the battle. It says I won. Then "error". I go back to fight more and see the "claim" button active, as I'm finished with only 6 wins. ???
Somehow this error, or opponent leaving, caused me to end my streak and even though it counted as a win for me(from 5 to 6 wins), all of a sudden I'm finished and can no longer fight.
