Maps that don't work :(
Campaign Mygeeto boots out any player except the server when they try to join.
Mustafar boots out players when Gizor Delso shows up.
Kamino boots players at a few points: (entering the facility, when shuttles show up)
Death Star boots players when the Rebels take the superlaser room (I think)
If you find a solution, great. If not, then just end the mission with the command before the boot trigger, or avoid adding these maps.
