Bug for conquest boss mission sector 1

I have tried this battle several times on pc and iOS, the result is the same every time. The battle with start with NS team (talking, OD, NSZ, AV) and marrow for the boss feat. The first few turns go as normal; however the first time I use Asajj’s buff dispel the entire client crashes on both iOS and EA client. I have wasted a lot of time and energy on this.
