I might be mis-remembering but I feel like I saw a cracked pot at the auctions??Yeah, I'm trying to get all the forms as well as complete the Pokedex and it's been such a pain with Sinistea. I can't even find a Cracked Pot just to evolve the phony form into Polteageist, all I have is the Chipped Pot.
I don't know I hope I am not misleading you.
If i recall correctly the auctions reset every 3 days (?) unconfirmed
