I ve had this several times now, I pick random and my mates choose their civs and we get the same civ twice in the team.
The intention of the difference between “Random” and “Full Random” should be that “Random” excludes any civs that were picked while “Full Random” doesnt, which is not the case.
So, “Random Civ” doest care at all what your mates picked and its super annoying to have a civ twice in the team.
This should be fixed so you cant get the civs from your mates picks.
