[UNET] Weird Bugs On Player Join.

Hello, I don't really get uNET yet, but i am trying. First. My menu scene is networked, due to the nature of it and so i have came across some really weird bugs. For one, every time someone connects to the host, the game freezes up. The client gets no updates to anything and stops moving. The Host sees two players spawn together and not move. The whole thing just freezes up. I am running the menu on an obscure port and ip address, this then is changed and everything is reset upon button press. I have no clue what is happening. I sometimes get a 'host bind {-1]' error as well as sometimes getting a warning of 'AddPlayer: player object already exists for playerControllerID'
