BUR #2878 has been approved by @evazion.
mass update away_we_go! -> memories_at_trifas
That particular outfit the tag is used for didn't actually debut in that Craft Essence but in Fate/Apocrypha and has an actual name in F/GO which is "Memories at Trifas". Tag should be updated to reflect the actual name of the costume.
(Memories "at" Trifas is the NA translation, Memories "of" Trifas is how it's translated from JP on wikis and stuff, whichever would be fine.)
EDIT: The bulk update request #2878 (forum #168185) has been approved by @evazion.
