I've installed a custom ramp and it works fine, the collision is okay. But after I scale it and make it longer it loses its collision on one end, and extends collision on the other as if there's an invisible floor near the ramp. Here's the model: https://drive.google.com/drive/folders/1iEPE1S6_xSt8l0bch_R89gvAhu_Z4wUT?usp=sharing
The physics only get reloaded after closing the editor. Have you done that? Also try to save the changes and then reload the level.
