Anyone seen this before?

OK, I'm in real late on this. I really can't make out what I'm looking at in that photo. It appears to me that the rafters are not pointing to the center of the ring. If that is what you are referring to as spiraling, you certainly do have it. Spiraling is not good at all.

The rafters need to oppose eachother and point to the center of the ring. There could be a complete failure of the roof if they continue to get out of alignment. A good ring design is like mine, where the rafters are fitted into slots in the ring. Literally impossible to get out of position, regardless of the yurt rocking and rolling in a strong wind.

If you are redoing the ring and rafter setup, I'd really try to get everything in proper alignment, and have the entire system anchored so spiraling is impossible. But again I really don't know what the heck I'm looking at. Whatever you do, think safety. You don't want a friend of loved ones to get hurt. Good luck.
