If I’m using fighting gauntlets and switch them out for a bow, the gauntlet model does not disappear from the character model despite no longer having it equipped.
This can be consistently replicated when switching weapons. I think it specifically only happens with bows and fighting gauntlets, I tested a few other weapons (but not all) and those seemed fine.
This is on the most recent public version of the game: Together Hotfix 7, January 31.
