Incarnation of Dread + Maven DoT

A huge dot seems to have been applied to the entire arena during a fight whith the incarnation of Dread.
It may have been cause by the graft skill return to dust stunning the boss and causing a desynch of sort, we can hear the audio cues bugging out at roughly the same time.

When reentering the arena: https://youtu.be/fd4h-hMc4wQ

PS: I have been having issues with boss desynching since the start of the league, ie black star casting avalanche and solar flare at the same time and its arena not rotating around, and exarch canceling audio cues and animations. I have been using return to dust since the start of maps.

Bug Report ID: #1,256,470,681

Can confirm this happened to me as well. I had return to dust equipped but no maven witness.

Also seeing this with Return to dust equipped.

Confirmed happened for me as well with Return To Dust equipped...

Yep I just had this happened to me as well, took off return to dust and it's fine

Can confirm, happened to me multiple times with Battering Uulgraft (Return to Dust) equiped.
When the boss reuses the flame aoe skill, the degen goes away, it seems that it resets it.

Happened with and without Maven witness
