It might. I saw in the preview of alpha 19 that the new tethers were a bit stringy. They weren't all that rigid. I also noticed that the Roche physican is doing pretty well. But a problem I saw was that after a while the rings fade away. I also saw that the larger parent body isn't effected by the Roche physics, but is effected by the tidal heating. Is that right?
I also saw that the tether object's would fade when you pan to close to them.
But since this is experimental, I hope this issues will be fixed.
