We are aware of this issue. Unfortunatly, we didn't manage to reproduce it. We are still investigating, but any piece of information regarding possible causes can help us a lot (spells used before dying, spell used before the end of the angel, stun before dying, etc).
I don't know what caused this but I do recall it happening near Iceblood tower I believe? just by it too. I was by Av waiting to rez him but he never left spirit of redemption form sadly.
would it be caused by something from the npcs near the tower?
