Baller will not collide with spline mesh

I created a rollercoaster 4 rail mesh and added collision, then used the landscape splines to make a track.

Player will collide. Even octa will collide, but the spawned baller vehicle will NOT collide no matter what I do. I have added boxes and simple collision and even that doesnt affect it.

Any ideas? Does baller just have some exotic collision?

I figured out that baller doesnt collide with ANY spline meshes, not even roads from Fortnite. I will issue a bug report :upside_down_face:
