So UGS came through again and fixed my spiral bug.  Things are looking even better when showing my bat project. They are looking good enough in fact that it is becoming clear I have an issue with my zero position and need to circle back around on my own code to work out some issues.  

I'm sure there are still little bugs hiding in here, that is how things go. But from my initial inspection it now appears to be rendering everything correctly.

You can grab the fix from the latest UGS nightly build here.
