Artifact Weapons missing after a Gear Update

Okay, so basically, I’ve decided to play my rogue after not really touching it since BfA. A little while ago, I’ve used the semi-new feature of the game, the Gear Upgrade, and it upgraded all of my gear, emptying my entire bags as a result. Now the funny thing is, it also destroyed (seemingly) my Artifact Weapons and I no longer seem to be able to unlock the Outlaw hidden appearance. The only Artifact that survived is the Assassination one, which IDGAF about to be honest. Do I need to level up a whole new toon just for the sake of getting that appearance? Come on, why is this game so buggy recently? That isn’t supposed to happen now, is it?

The stuff you have on you is usually sent to the mailbox. May be a silly question, but have you checked? edit: too late ^^
