PC
Version : 2.12.0

I won the first fight, was just about winning and finishing the second one, when my game remained stuck in the second Battle, never progressing to the third one. the time was still running
During this state i was able to use the left side buttons: canceling "Auto", using "Info" and changing the speed x1/x2; i could press Escape and the quit menu came on, but i later on found out that i couldn't Skip Battle or Quit Series, Continue worked returning me to the fight. 

After quitting the game came back to TTA just to find out that the 2nd fight was considered a win and I auto lost the 3rd one.
