That is a little problem... It happens... when playing on 4-man... so... Pat must fix it.. (i experimented by my self)
Or... solution:
One start and load the map fast and move..
The second one loads and moves
3rd demorate more than the second and move
and the 4th is the last loading.
That a solution because the problem is that you are all in the same place, so, if you move, you solucionate that.
