I bought the game yesterday (03/24/2020), today, me and my friend tried to play a multiplayer match against other 4 AI, the host (me) started to load the game and being stuck on the "Waiting for other Empires" stage, and my friend didn't started to load, i have all DLC and he doesn't, we tried again with he being the host, and the same thing happen, i am thinking to refund the game, if any solution appears i won't.
