Why is it that my FAR-ortho crossroads and t-intersections never want to be placed at the correct angles? they'll rotate through all kinds of crazy angles that I don't want them at, but not the ones i need. I've got to straight FAR piece at either end of where i want the intersection to go. a regular FAR straight piece plops down there with no problem at all. i've bulldozed everything for a ten square radius. I'm very frustrated. what am I doing wrong?
