Forbidden Flame/Flesh "Unstoppable" Node not Preventing Stun

Bug Report Number: 2,214,861,070

I am playing a Cyclone Chieftain with the Forbidden Flame and Flesh for the Juggernaut's "Unstoppable" node.

Node appears to be allocating properly, my character sheet changes to "Stun Immune: YES" when I equip it, and I am getting the other buffs such as the movement speed.

My Cyclone is being interrupted by attacks after I un-allocated Unwavering Stance. I can't be sure, but I think it is happening when my character blocks attacks.

Again, didn't experience this with Unwavering Stance allocated, and it's incredibly noticeable as it totally stops my Cyclone for 0.5s when I get hit.

Basically makes the character unplayable, and in my instance, the two jewels are worth a hell of a lot less since I still need to spend skill points on pathing to and allocating Unwavering Stance.
