The North Wind's collection is bugged
QA Embed
So I’ve pretty much already done all of the requirements to obtain this item save for the Adventure.
Now that I did, I didn’t get the collection completion, even though I’ve already obtained the Silver rank for the Punch-O-Matic adventure.
EDIT: It seems like relogging did the trick. I wonder what caused it though.
Did you open the silver reward box from the adventure? The chests dont count until you open them.
