This bug definitely still exists and I'm assuming it's related to Eccea's Arcane Blaster. Just got the bug myself after picking that gun up and enchanting it with the shot splintering. Using Scordeo's as mainhand as well. Can upload a save of the bug freshly occuring if more examples are needed.
Add DeYvu8 and XQrdGv to the list, in the "You Control Critical Role" video they just released.  Blah, false alarm. There is two codes in the video but both are old ones we already have. Bummer.
