I managed to make it work by changing the way I spawn my players. Now the Server is also listed as Client. Before he was only THE Server. I also had some networking mistakes.
My recent issue is one I am struggling from the start and is about displaying player stats on the HUD separate for the Vampire than for the Villagers. I cannot make it work in the player controller (as I understand I should) because I do not know how to see what character is the Client controlling. Before I had a IS SERVER function that worked because the Vampire was Server and not also Client. But now, when everyone is Client I cannot make a difference between them.
I have searched the internet but I cannot get something specific on this simple issue. There is something I am overlooking.
BTW, I spawn my players from the game mode, but spawning widgets doesn’t work there for some reason.
