I recently came across a Ghostly Aura which I wanted to equip or trade for Twinkle Aura, but I am coming across an annoying issue. When I try to equip this accessory on my Spiral Culet which also has Regal Side-Blade and Regal Barrel Belly, I get the error:
"This item already has an accessory of this type. Remove it first."

I've tried removing aura from the piece of armor even though it didn't have one, but I still get the message when I try to equip Ghostly Aura.

I have 6/7 total accessory slots filled. On my Spiral Pith Helm I have equipped Regal Vertical Vents, Regal Bolted Vee, Regal Goggles, and Regal Long Feather. Along with the Regal Barrel Belly and Regal Side-Blade, I have 6/7 total accessory slots filled.

I sent a Bug Report on this in-game, but thought it would be a good idea to also make a topic here in the forums.

(also on a side note, I think with what I have equipped I look like a Egyptian God!)
