So today I did a combat mission with my Rey team. Even though my Rey is R7 with ultimate, the sniper droid decided it was going to just one shot half my team even with all the extra protection she added to everyone. But in wave 2, my JTR was left standing and then this happened. Once she was alone, the droids kept attacking and she kept dodging or deflecting. Not sure why this happened, if it's a bug or what.
As well, in the case you ever wondered, yes the B1 stacks will go past 999! But if JTR is by herself in front of them, it won't matter how many stacks they have. I had to just forfeit because we had a CPIT to run tonight.
