Nightsisters great mothers

During game play with the Nightsisters using Great Mothers as lead with Morgan, night trooper, death troopers and spirit. When I use that team Gmothers goes first then does her next ability and then continue using that ability that's it. Will not go to the next character timer will end battle is defeat. I've restarted my game, I even Uninstalled it and reinstalled it. Still does the samething. It's only that team, the other teams does just fine. Please look into it if you don't mind.
