Anticipated The Witcher 3: Hearts of Stone (Expansion) Limited Edition

[CheapAssassin]

OK.. dumb question.... Actually I shouldn't have done this.. I am almost done with Witcher 3.. problem is..

I play my Witcher 3 (Region 2 / European disc) in my US PSN account... so if I buy this GameStop PS4 expansion, do you think it will work?? =/

I tried to download those free DLCs last night from US PSN store, but they dont seem to work with my Witcher 3 Region 2 game.

Any idea how to work around this? Do I need to buy a Witcher 3 R1 game?
