change maps:

map mp_estate
map mp_favela
map mp_highrise
map mp_derail
mp_checkpoint <---karachi
map mp_quarry
map mp_rundown
map mp_rust
map mp_boneyard <---scrapyard
map mp_nightshift <---skidrow
map mp_subbase
map mp_terminal
map mp_underpass
map mp_brecourt <---wasteland


add fast_restart at end
EXAMPLE:map mp_rust;fast_restart

You don't need to put "fast_restart" but just map mp_swag and the restart is automatic.
