I have an adult male and an adult Pastel Woma female. I also produced about 12 babies this year. My two adults, I have never really seen anything with them. As for babies, I have about 3 or 4 that do wobble. With that said, I have never seen any of them severely corkscrew or have issues righting themselves. I do have one of the wobblers that is more devere than the rest, but he doesn't really spin. He just gets very excited at the sight of food.
Put it to rest. Womas do wobble.
I also have a HG Woma, and I have seen no evidence of him wobbling or spinning at all. I only have the one though, and have not produced yet, so I have no definitive conlusion to be made on that mutation as of today.
