Can't find some items in the marketplace

Is this still an issue for 1.2.10.2?

Yes

The listed items where only available for a limmited time. If you aren't logged in with the account you "purchased" them with you won't be able to find them.

Are you able to find them in your inventory when you scroll down to the bottom of the marketplace?

No

If you didn't get them while you could, you can't get them anymore. They were avaiable for a limited time, like the Minecon 2016 skin pack.

Purple Parrot Party Palace is available again through the marketplace, but the others were available for a limited time only.
