Looks like I've now run into a bug/glitch for Mortal Kombat Onslaught. I was playing the Jax story mission, and it transitioned to the next wave followed by my characters fully charged, waiting to activate their special skill. 2 characters were charged during the transition, and Kitana had just filled at the peak of the transition and decided to activate seemingly before the other 2 characters. On Auto-Battle, the characters usually automatically activate based on who filled their meter first, so I'm not sure if Kitana triggering hers first before them broke the match or what?
I did quit the match by selecting Pause and then Quit off camera/recording.
