[item2=Tigarch] It says Melody Item, but it's actually a January 2010 collection item, according to subetalodge and to where you can find it. So...the Melody ref is by mistake?

If it was Collection and not Melody, it probably got mistakenly shuffled into that rarity when 'Melody Item' became its own rarity. Maybe post about the rarity mistake in Art/Content/Item Issues in the P&B forum.

Will do, thanks for answering :)
