Bulwark hitboxes are inconsistent with Trauma staff

EDIT: Just found this is a duplicate report. This is acknowledged here Bulwark Shield interacting weirdly with Trauma Staff after patch

Issue Description:
Bulwark hitbox interactions are inconsistent with the Trauma staff. Quite often, even if you have the middle marker behind the Bulwark, it will hit the shield instead of opening them up or throwing them to the ground. It also doesn’t help that the stagger immunities are not in line with the stumbling animation durations for all ogryns, the immunity is longer than their recovery animation.

Steps to Reproduce:

  1. Play The Meat Grinder as The Psyker Psykinetic
  2. Equip a Trauma staff
  3. Perform multiple fully charged secondary attacks just behind of the Bulwark
  4. Observe how at times nothing happens or the Bulwark simply makes a 180 turn.
  5. Observe that if you release just after the stumbling animation ends, nothing happens except some damage if it did not bug out and hit the shield.

Mission Name (If Applicable):
Any, but fastest to replicate in The Meat Grinder.

Platform:
Steam
