Yeah... does it fail to collide with the pole, like it does
on my build? Collisions are missed here.

It doesn't go through the basket?

Also: you mean, it disappears through the hole in the ground under
the ramp? In other words: is it correct that there are no missed
collisions? On my build I see no missed collisions for double precision,
only for single precision.
