I'm sure this has been reported, but I can't find it at a cursory glance so here goes. In the new ZCC alert you fight Harley and Catwoman as sub bosses. If you fight Harley at the first encounter and then go on to fight Catwoman at the second encounter and your group wipes, Harley respawns in her place and you get no loot when you kill here. I highly doubt this is working as intended. Please fix. Thanks.
I believe it is a still active bug, even, as this happened either yesterday or the day before to my team.
