Ahsoka Tano gameplay freezing?

I ve had 3 different battles in different events where iVe use a Spectre Team with AH lead and the game freezes up or gets stuck in a loop. I use A's 2nd or 3rd ability and the game goes on hold. You can't make select a move or the enemy doesn't take a turn.   You can watch the time run out if it's a timed battle, you can look at stats for each person, you can change the speed of the gameplay but nothing happens. You either watch the timer count down to defeat or you have to forfeit the match/ exit the game.  Anybody know what's going on?  Any help would be appreciated.  Thanks.
