Anyone have any issues with the Mastery of Hate raid? We killed all 6 mothers, but by the time we were killing the last one or two, the first one had respawned as unattackable but was still spitting out the babies. When we did kill the last Mother the Master of Hate didn't activate. We hung around for a bit after that, all 6 mothers respawned while we sat there and they were all unattackable and spitting out the babies. Our strategy was to kill the mother starting at the north and moving around the room and after killing the last one kill Master of Hate, but that didn't happen. Any thoughts? Thanks all!
