Bug Report ID: #434585840 Doryani invisible after fight, possibly due to Devour

I finished the Act 3 boss fight with Doryani by using the Devour skill to consume Doryani's Triumph. This was extremely satisfying. However, Doryani was invisible throughout the entire cutscene after the fight.

This may partly be because Doryani's Triumph never entered its second "phase" where Doryani flies around in his little escape pod. Thanks to a combination of heavy stun, freeze, and my burst window coming online, I was able to burn the boss down before Doryani's pod finished launching.

I grabbed the recording from Steam: https://youtu.be/4oTxpUVQkTA
Watching it again, Doryani looks... troubled.

I'm not sure if he was actually glitched the whole time or if Devour did it.
