Connecting with client causes n+1 players to spawn

Hey guys,

Networking n00b here. I just completed this fantastic tutorial here:

http://www.palladiumgames.net/tutorials/unity-networking-tutorial/

I created the following two scripts:

• A player mover script: http://pastebin.com/Zc7eQTSr

• An authoritative server script: http://pastebin.com/egUQz8yC

Now, I have 1 question and 1 problem.

The question is: How do I use OnPlayerDisconnected to destroy the player that is instantiated when they join? It's in the server script but it isn't doing anything.

The problem is: If I connect the client to the server, the disconnect it and reconnect it, additional cubes spawn. I could be mistaken, but it seems to be 1, then 3 cubes, then 5 (maybe 4?) cubes. Why is this happening?

Any help would be really fantastic, as I'm still trying to learn this type of programming. Thank you!
