Thanks for the suggestion, but its not fast enough. I use the Dev Authentication Tool to login to EOS before PIE launches which makes the clients login slower than the server, this causes them to be desynchronized in the beginning. I need the “number of expected players to join” from the get go.
Currently Connected PCs are added to the array OnPostLogin in the game mode.
When setting the Number of Players in the multiplayer settings, that Integer is stored somewhere, that is what I need to get.
