The first game I played it was on Nomad. I lost. I thought I should ban it. But wait? Nomad isn’t on the map pool!! How can I ban it or play it.
Next game I played was on Baltic, which I haven’t checked but I think this isn’t on the map pool too.
Can anyone confirm!?
Map pool rotation recently updated.
Just restart the game and the new maps will show up.
I restarted after the 1st game.
I saw other people reporting the same issue. They probably going to fix it after the maintance.
Enjoy while it lasts 
It’s fun to get to play all the maps that people normally skip through 
Lol the new 1v1 rotation is literally just a bunch of Arabias
Ranked will not be ranked for me until we have all maps available and no map bans or civilization selection
