Cortex drops not happening after leaving during dying animation of final boss

Bug Report ID: #496914685

After killing the final boss and leaving with a portal(handcast portal gem) during the dying animation, the animation seems to have disappeared and returning to the boss arena resulted in no drops happening even after extended waiting. Point of leaving was around the portal device breaking down part of the animation. Leaving the map and returning through a portal does not seem to fix it. Portal to leave the boss arena also doesnt appear.

That is how it has worked for years. Applies to Maven, 5-ways, and I forgot what else that has a death to loot transition time. Drawing a blank now why it was changed that way if it was dupe exploit or related to some other change, but someone must be in the instance for loot to generate. If you die while those instances are transitioning to loot, you need to stay dead, let the loot generate, then resurrect.
