More importantly, elevated rail now collides with rail support, which means that it is impossible to construct any elevated rail when this issue persists...
And FYI, 0.3.2 does not have this issue (thankfully).
just roll back to 0.3.2 for now. I ll try to fix it in meantime
it's caused by how I added collision mask
because previously slightly curved rails were buildable on wooden platform and for some reason you can't add colision layer to them without adding them to elevated rails as well and it's kinda a mess but I have idea how to fix it
