Conquest Sector 3 Boss Freeze

So…I was able to complete it with SLKR.  I do want to say that my issue was not the node mechanic where you have to exit using the node ability.  My team was Leia, Captain Rex, R2, C-3PO and Chewy C-3PO.  Anywhere between 7 and 17 kills the game would freeze even if I let it timeout O wouldn’t get credit for the few kills.  I was trying to get feats done with droids while completing the node and I guess not.  My issue is a bug based on team composition it appears.
