Ares Sunder countdown tile staying on board after death [Devs Aware]

Playing in Iso-8 Lab: Canada in the Cloak & Dagger required node, round 5. I have C&D, Riri and G4mora, and I've already killed off Doom. Ares fires his Sunder, and then I finish him with Riri's Selfless Intervention. His Sunder countdown tile stays on the board even though he's dead (not just airborne, I checked). I matched it away before I thought to check if it was still counting down.

Enemy Ares was low on hp, used Sunder, and the CD tile stuck around even though he killed himself in the process.
What was interesting this time? The CD time stayed at 2, and did not tick down.
I saw saw it more than once, but I remember it happening for sure in the Doc Ock required node of the first day. I had Doc Ock 5*, 3* Cap Marvel, and Doctor Doom on my team for at least one occurrence of it.
I'll try and duplicate in day 2 and get a picture, shouldn't be tough.
Additionally, unlike before, when you use Ares 'Sunder' to finish a match, he will now take damage. It used to be the case that his power 'stopped' if the damage component would kill the last opponent, preventing self-damage. But he will now take damage regardless.
This used to be a thing, numerous fix attempts were made, and then it finally was for about a year or so.
But now it's back.
Donno if it's 100%, but anything higher than 0% needs to be looked at.
