After the firmware updated on mine I was left with un-programmed Radions, so I had to re-import "Jon's Graph," I time shifted from his 11/11 to my 8/8 and I didn't have any issues. I'm not sure what it takes to qualify as a bug, but this wasn't an issue for me.
Again, the only issue I had was that it wiped my lights back to defaults and I had to regroup/rename/reprogram. Other than that the platform is working great for me on OS X Mountain Lion AND on my old Windows XP laptop. FYI - Internet Explorer is NOT supported, it requires Safari, Chrome or Firefox.
