Had to do with the move to a new server.. in the end it was a 'problem' when i moved over since the ip was already given out since i forgot to take it with me. I should really fix all tf2 servers with that favorite moving thing.. that way it doesn't matter. But have not come around to do it.
If the IP is still in LZ's posession, you can run a server on it, to give it a ID with the favorite movement options, and then pop it over to the new server. unless you mean that the IP is no longer of LZ...
