Wow I totally missed that thread lol. I feel like the wobble was the most obvious when I was opening drawers in the rack and putting rats in. Maybe that was stressing her out or she smelled the food? She also may just be settling in. Like I said it's only been a few weeks so she may not be 100% comfortable yet.

it would make sense that any form of stimuli(food, opening the tub) that excites her in any way would cause the wobble to come out.
