I’m 100% sure they were stuned and confused i saw the icons cause it was tricky team for me.
Also my second thought was: Didn’t i just killed Erica? I spent a few seconds to realize what happened and think again what did i checked before that. So here is my steps after killing Koa:
Erica is very low health (138 HP i think) and i have only 1 hit to do with my Green Carl (he has extra dmg to alerts).
I double check that Hunter is stuned and Sandy confused (wait to actually see the icons)
I’m ok with this and i do my final hit to Erica. Watching her die with 320++ dmg. That was my last hit.
After that she revives Koa and i stay frozen.
Also with confused characters that they use their AP. Happened twice with me in auto mode and i thought i was wrong. Sometimes in auto mode there are visual bugs but the fight is normal.
I red once more here from another player having the same problem but maybe it was a visual bug too.
However in this fight i was in manual mode and checking every detail.
