Duels: error starting

[Суворов-2787]

There is a blue post

There was an error starting your game. Duels Error

My guess is they are lazy introduced the core cards to early and didnt have them on a no allow list from deck creation. So anyone using any core cards in any deck list will get the game launch error. 50 Bucks when new patch comes out and core cards are enabled it all magically works again. Lazy Activision and Blizzard tsk tsk tsk. Beyond your programming skills?
