[Kuva Bramma / Bows make melee weapons glitch]

Happening for me too, The Dread and a Staff Zaw.

[frame can’t attack nor go into operator mode]

This has happened to me on the Plains of Eidolon, couldn't preform manual reloads for the remainder of my free roam. Lucky I was equipped with the Zenith, really annoying but sufferable IMO. It is tied to the new knockdown recovery; of this I'm certain, if you are performing certain actions and are knocked down regardless if you recover ore not this happens

[Steel Meridian: Protector requires Destreza Prime handle]

So I'm trying to grind steel meridian standing to get to the Oberon Mods and when I went to check what I needed to rank up, it said I require the Destreza Prime Handle, however when I looked at the current relics, it's nowhere to be found. I looked it up and this prime weapon is retired, and Protector rank is supposed to require the Redeemer Prime Handle. I'm working on getting a screenshot up, and I've yet to test if this is visual only; I'll get a Redeemer Prime Handle to see if its visual.
