That may help. Its certainly not needed.

You need to try to narrow the problem down yourself. If it happens when a player is kicked or quits it likely that there's a problem in your kick command or OnPlayerDisconnect. Add some prints and see what gets executed before the server crashes. Posting all that code will get you no-where. Who would want to find and download your includes then test? Not many people.
