I did the first two battles in sector 3. One feat is attempt to inflict stun 100 times. I used my slkr squad and did his stun ability once in the first battle and three times in the second battle. I literally spent 50 crystals just to refresh my energy so I had enough to go in and take a picture of my roster to show that FO is the only team I used today. Am I to assume that it doesn’t count because when slkr is stabbing enemies with his lightsaber, they are actually inflicting stun on themselves?
Edit: I should mention I fought two battles with JKL right after and the stuns counted just fine.
