Last night while doing Totems during the King's Fall Raid on hard mode, me and another team mate on the same side (left) acquired Deathsinger x10 at the same time. We ended up losing the aura protection. I've had another friend report having this issue. Fortunately we manage to get the aura back quickly with the third person returning back from delivering their Deathsinger power. I'm questioning if the latest patch has introduced a glitch into this particular raid battle?
