Update:
Nevermind the original Issue, it appears I found why it crashes.
What I am trying is this: Client connects to a kind of test setup of a login server.
They enter their Login Data, click Login, and the login server executes the load command for the Player.
Without any Login stuff and the load command being issued right after the button is clicked it works, the Player is transfered to the other Server just fine.
If I send the Login Data to the Server, the server verifies it and tries to call the command for the Player it crashes, I tried executing the Console Command as replicated on client, but same result, any Idea why this might be?
