Online TPS problem

Hi everyone. I’m developing a simple online third person shooter. It works but I have a problem when client disconnect from server.
I use a peer to peer approach, so one player is the server, other players connect as client and I use RPC calls for syncronization.
The problem is for projectile, when a client player disconnect and reconnect to the server he will be re-hit from the projectile that have hit him before disconnecting from the server. How can I solve my problem?

I think this is the problem (RPC buffer), but the server should clear RPCbuffered when a client disconnect:

function OnPlayerDisconnected (player : NetworkPlayer)
	Debug.Log("Server destroying player");
	Network.RemoveRPCs(player, 0);

but it doesn’t work
