since i am new here, idk if this is categorized as bug or not

i have 2 eq, they're black ribbon and momo headset. in the item detail, they're categorized as Accessory . but then, when i equip the item, they replace my Cleric PIya Hat

so, are black ribbon and momo headset categorized as Accessory ? and why do they replace my Cleric Piya Hat ?

Grazie


Sincerely, Florence
