I have been playing Endless Space for over a year on Steam with a friend who I also got the game on Steam for them. This past week we both loaded the mod "A Galaxy of Endless Diversity" the mod shopping mall on this forum and have both been playing it with no problem. Now when we try to do a multi-player game together it shows the game but is grayed out noting we do not have the same version. Both of our games show in the lower left corner that we do:



Disharmony 1.1.58

A Galaxy of Endless Diversity 1.5.0



Any ideas why we are having this problem?
