cannot move at start of mission

[1para{god-father} 105]

Having an issue with my mission when we start and spawn in a few players cannot move at all they are stuck ?

I have the following in my INI.

if ((!isServer) && (player != player)) then
{
 waitUntil {player == player};
 waitUntil {time > 10};
};

If they kill themself and respawn they then can move fine, Any idea why this happends ? is it something to do with loading stuff up at the beggining of the game ? if so any way round it ?

It only happend on hosted server

Thanks
