I have successfully obtained a Pokémon trough an auction.
The auction is over, the amount I placed has been deducted from my
account but I can't find my Pokémon. Where do Pokémon from auctions
go?
It can sometimes take a while for the Pokemon to be transferred
after you win an auction, but you should get a notification from Auction House when it does.
As posted above, it can take a while for the results to post.
Typically it will be sent to your current party if you have less
than 6 in it, or it will be sent to your poke box. Hope this helps!
