I was playing Item Scramble and came across a scrambled item that, once unscrambled was totally unfamiliar. I looked it up in search subeta and it wasn't there. I figured, okay, I must be misspelling something. I hit submit anyway, because I couldn't figure out any alternative and got it correct and got the points for it. However it was totally blank under "correct answer". The item was "earth brilliant crystal"

SubetaLodge has it listed as a Rarity 300/Staff item. Still, it might be nice if items not available to all users could be omitted from the game.

agreed! Especially when the item doesn't show up in shop search or subeta search. Though I did eventually find out that it will kind of show up in account search (if you search for brilliant crystal, it shows up in the list).
