crashing in TB, phase 5/6 on Malachor

My guild sends two days on Malachor.  Yesterday, while playing on my iPad both the Pirate King Hondo and Lord Vader squads crashed the game on the first AOE attempted.  Today, from the same iPad, LV crashed it again.  I switched to the PC client on a laptop that is not high end and PK Hondo's squad was fine.  Not sure if all those computes from DCTs AOE is crashing my iPad or something new happened with a patch since we last had TB and LV's squad played fine both phases for me, from my iPad..

On a side note, a don't know if the New BB squad's riposte is working as intended in conquest.  I have been grinding out the feat and have yet to observe NuBB with riposte counterattack like Dooku constantly does regardless of in stealth or not.   I only need the buff for the feat but still...

Finally, whatever developer created the Pirate King Hondo unlock journey.  Bravo.  It's the first journey event that was just enjoyable and did not feel like a grind that I looked forward too as much as a colonoscopy prep session. I hope that developer (or team) get some sort of reward for creating content that the players enjoyed.  That's what this game is about, enjoying SW content.
