same here. Just rerolled my launch druid for the season and after initially saving a slot with the default club/OH I picked up more gear including 2H and it won’t save if the original 1h/oh are not equipped. Weirdly the barb I started S5 with is still working fine though.
edit: For druid managed to trace the bug to saving a slot with the default 1h/OH combo equipped. It was repeatable on two more test characters. Fixed by creating a new one, immediately buying something else off the weapon vendor and equipping, selling the defaults, then wardrobe is working correctly now. Not sure what will happen if I go back to 1h/OH combo though later on.
