Got knocked unconscious, bard song mezzed my target, popped up with full hp
 

So, title says it pretty straightforward, I won't be purposefully trying to re-create this bug..

Scenario:
- Level 20 bard
- Was fighting 2 goblins in OOT and was about to die.
- As I got close to dying, I stopped my song rotation and started singing Hymn of Restoration and twisting Kelin's Lucid Lullaby. Hymn landed on me and I began to twist Kelin's when I was knocked unconscious (purple clubbed). The Kelin's song executed successfully while I was down and mezzed the goblins.
- Regen tick occurred when purple clubbed, and i popped back up, but at full health.
