Great Mothers taking bonus turns every turn

Not my videos but have had this happen against an alt account in squad arena

https://old.reddit.com/r/SWGalaxyOfHeroes/comments/1fbwqb3/great_mothers_is_bugged/

With their lead reading "If all allies are Nightsister at the start of battle, at the start of each encounter and end of each turn, if there are no _____ inflicted with _____, Great Mothers removes Ability Block from themselves, gains the granted ability _____, and takes a bonus turn." the bonus turns are tied to all allies being nightsisters and should not be happening when the team contains non-nightsister members.
