nono, u r ALLL wrong....
example:
I made a map called "CargoPort-101"
someone joined to test it, and after they left, i did some work and uploaded it again without renaming it.
then when the same person tried to download it and play it again, it didnt overwrite the old one in their base thus they get the error "Bad inline model."
so, after each test, be sure to rename it...
