SplineMeshComponent does not collide on Android

[shpen]

I followed the instructions here:

To create spline meshes in C++, and it works fine on desktop, as you can see here:

My problem though, is that when I deploy to Android, my vehicle falls right through the floor. Has anyone else had this problem?

I set my mesh's collision like so:

SplineMeshComponent->SetCollisionEnabled(ECollisionEnabled::QueryOnly);

Thanks.

Actually, exporting to Windows executable also suffers this problem. It seems that the collision only works in the editor.
