Multiplayer spawn points blueprint

I have tried your solution and it doesnt worked. I dont know what I am actually doing wrong. If I override the FindPlayerStart method I get the error Couldn't spawn player: Failed to find PlayerStart what I have done: Creating an array of controllers which gets filled at BeginPlay and just choose the first one out of the array within the FindPlayerStart function override. But the FindPlayerStart gets called before the GameMode BeginPlay function -.-"
