Collision size won't change?

[Koopa124]

Hey guys, I have a unit called an Onager, and it has a custom skin/model of an Onager. Problem is, no matter what I set the collision to, units can still pretty much move right through it. +rep for whoever tells me what's wrong and how to fix it.

check the movement, if it's flying then thats the problem

It was set to none, that might be the problem. I'm checking now. If it works, +rep for you. Thanks.
