Resurected IK not Aflame anymore

What you were expecting to happen, and what actually happened?
I was fighting against a team with IK. I killed it, Immortal trait triggered. Visually everything was OK (all traits unlocked), but when I got hit my troop wasn’t set on fire (Maw, so no Fireproof or Impervious trait).

What are the steps to make it happen again?
Play against IK team, kill it, he must resurrect, then get hit by him. I noticed it only once, but I’m sure about it and I’m sure earlier in the same fight (before the resurrection) the IK had no problem setting my Maw on fire.

Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post!

I think I noticed this at some point. That and Ancient Horror from Daemonic Pact being spawned on fire from IK killing Gorgotha or similar.

I’ve seen this as well. A fully traited resurrected IK fails to burn an enemy.
Later in the fight, the resurrected IK starts burning after a 4 match by a fully traited Jarl.
