Hi!
Quickly: at the end of the first level (multiplayer) the game instance has array variable Team1 with its players and Team2 with its ones. When I move from the lobby to another map, I make the server access to the game instance to say other players in which team they are.
Well, the array are empy. Or better, if i print theri length, I see the correct length. But when I print the name of members in a FOR LOOP, nothing appears.
the GameInstance is not replicated (synced through network), so each player only has its own local copy and doesnt know anything about the others. you should store your team arrays in a GameSTATE, which IS replicated to everyone. that way all players will know who is in what team.
