Zealot "punishment" feat does not grant Uninterruptible at max stacks

Issue Description:
I’ve been using it for a while with a heavy sword to test it out, and the Uninterruptible buff at max stacks just does not work, or does not proc. I know what it’s supposed to be : you should not longer get stunned by melee attacks, like the zealot feat ‘Thy Wrath be Swift’. But that does not work.

Steps to Reproduce:

  1. Go into a mission with Zealot
  2. Get max Punishment stacks against a horde
  3. Get attacked in melee within 5 seconds
  4. You still get stunned
