I seriously hope something is done regarding this too....
It has become an almost pet hate of mine, especially with so many courses using the basic Easy Roads and thinking it suffices. Quite simply, any course with this addition, can be impaired.
I seem to be able to hit the edge of anything these days on various courses, but hitting the edge of a mesh AND these dreaded cartpaths, now cause me to cease playing the full round. Granted, I could be used to too much perfection with these high quality courses also available. However, the strange bounces returned from hitting such odd angles, makes golf appear ping-pong.

Not Easy Road in the image... I know. There is no danger of seeing your ball disappear under an Easy Road though...

The above images, are examples of what we see.... however, you'd expect the cart path mesh to actually be below the Unity terrain in a similar way to the pot bunkers.
Whilst things are not yet possible obviously, hopefully this will change in the future. Whatever is done... can I honestly state.. anything used by Easy roads is far far far from smooth, perfect, playable, pretty, eye candy or whatever you believe it to be. It's simply something we've yet to see as a breakthrough, within the CF.
