[2022] Bug Report: Level 4 Knockdown Shields

@lyntonjmoore Good catch on the ping thing, it's gone for me now too, I just didn't notice since I've been focused on Gun Run. We'll make sure that's tracked. 

As for the Level 4 shield, that was actually a change made a little while back, at the start of the season. The self-revive was removed and the Guardian Angel (health and shield on revive) perk was added. 

Notes 

Knockdown Shield Gold Perk

• New Perk: Guardian Angel (Previous Backpack Perk).
• Self Revive removed from the game.
