Mule Kick Bug is Back

Can't express how frustrating it is when they leave a bug sitting in the game for months, fix it, and then it's back.

And it appears that's the case with Mule Kick in Season 3. The 3rd weapon slot is bugged; I've seen the gun straight up disappear when doing easter egg hunts which means I lost all progress and had to quit.

Also seen the 3rd weapon slot downgrade in rarity? Was at orange and a round later it went back to no rarity?
