the only thing i can think of, if it lets spawning at the green base, is something in the 'red' airfield properties that FBDj doesn't like.
will have a look if i can see any obvious differences in the mis file.
whats the mission name on the server TOAD?
Edit, found it on the server page.
Just checked for myself on the server and same result.
Do you remember when you were first setting the server up TOAD, and there was the same problem of snackos Normandy map, and i kept getting kicked spawning of the red test runway base. did you ever work out why?
