It has been months without a fix, I would love it if they just skipped the whole Kimmes the Historian thing and made it so that anyone who has 30HOM natively would just get an unlock achievement chest or something that gave you all skins so you could actually access them.
I mean once you get the items into your inventory there’s no point in accessing the NPC anymore, so tying the acquisition to a physical location is alright, but not worth denying thousands of players a dozen+ skins they already should have unlocked.
