Please specify the problem more directly.
I start a server, then i put a spawn brick. I set up a minigame,and instead of spawning on top of a rooftop, which is where i placed a spawn brick,i spawn on a car i made out of bricks, and the server seems to think thats where a spawn brick actually is, so i get spawned there every time i respawn.
EDIT: That should help you understand my problem.
