@Pertudles : The issue is probably not a flaw in the game client or in the game host running on the megaserver. It is most likely related to your player account and/or to the process that you used to obtain and install the Summerset "chapter".
If the keys were obtained gifted from the Crown Store, you might ask for assistance in the following forum section: Crown Store and ESO Plus.
Else, please ask for assistance in the Customer Support section of this forum which corresponds to the platform on which you play TESO:
They were purchased through GMG I am told, the weird thing is summerset unlocked on EU just not NA.
EU unlocked but the same account NA server didn't?
You definitely need to contact support directly at the link at the top of the page saying "Support" and click "Submit a Ticket", or click that which I copied for you to link directly to.
They should be able to easily correct this for you, but you need to hurry and submit the ticket so you get the psijic villa on NA server.
