So this is a new devastating bug I just now encountered while doing a Tier 6 Sith Triumvirate Raid. During Phase 4 I used Unbreakable Will on my B-1 to stop and Annihilate from Nihilus. Continuous attacks from other NPC's cleared all stacks of B-1's Droid Battalion. When I used his Special Ability to give my General Grievous and Droideka some extra Health and Protection both times they were instantly Defeated. I assume this is not a new Bug but I am notifying the community so this does not happen in the future.
