Standalone/Packaged game losing phsyic asset collisions.

Hey guys,

I was wondering if anyone has run into the problem where in stand alone and packaged builds collisions on physic assets stop working.

I currently have a skeletal mesh with a custom collision channel on it and am firing a projectile into it. The projectile causes and OnHit event while playing in editor but not in a stand alone game.

I have tested the custom collision channel with a standard static mesh component (a cube mesh) and it generates the hit event like normal.

It would be great if anyone has run into this and has a fix or if anyone has any ideas on how to fix it.
