While playing with a tiny potato, I accidentally equipped some baubles by right clicking them (groucho glasses), afterwards i equipped some others via the same method ( scarf, thick eyebrows).

I couldn't take them off since they didnt appear in the curio inventory.

Checking the player.dat NBT showed that they had been equipped under "curio_player_armorstand".

Pictures show my player having cosmetic baubles that aren't in the curio inventory.

Interesting bug, thanks for reporting 😄 @ochotonida I'm afraid baubles can be equipped in curio_player_armorstand, and then never removed since they're hidden.

Hmmm, seems like I messed something up again 😅
For the time being, you can remove the items in the invisible slots and prevent new items from being right-clicked into them using the command /curios lock armor_stand_curio <player>
