I recently purchased AI War:Fleet Command with the intent of playing Co-Op with a certain friend. He bought the game about a years ago and have two expansions installed (Zenith Remant and Children of Neinzul). I bought a bundle and got 3 expansions ( Zenith, Neinzul and Spire) but have installed none so far.
Do we need to sync our Expansions and Patches to be able to play Co-Op?
Currently I have installed the base game, no expansion with patch 5.087
