I've noticed all the old maps i have lying around on sauer, from the previous edition -- none of the glitchy cubes (other than one-way cubes) are working as they used to.
Ladders/pushing cubes, etc. How do you guys make them nowadays?
Also, if anyone remembers these silly ramp things, where you charge up momentum by running backwards at the top, then you slide down it at crazy speeds:

Is there a new method of making these too?
