How to stop flying past when bottom-solid = false?

[Feli0TheWriter]

I have a problem. I'm implementing grind rails into the game, and for the rectangles it's just fine, but when making right triangles and quarter pipes have bottom_solid = false, you can just fly past at high speeds and completely ignore collision with it. Is this a bug?

Bottom_solid = true

I think I should mess with this here, but I don't know what to do..

EDIT: That is intentional. There isn't an easy way to change the physics so that top_solid -only pieces perfectly detect that you're about to land on them going horizontally at that speed. That would mean perfectly knowing regardless of terrain shape that the player was "above" the terrain before landing, a headache even the original developers didn't seem to care about.
