When was she ever perfect? She had muscled jumps (especially the axel) and ugly tanos for her entire senior career, which started unraveling pretty badly last season. The only thing she had going was mad consistency, which also started slipping due to body changes, possibly injuries too. Do you remember how she made funny faces after her programs because she had already started making mistakes? I assume that was unusual for her then but it was a clear sign of what's to come. But even if she was perfect half a year ago, now is not half a year ago and an athlete's condition changes all the time. Of course she would be having the same problems, maybe even worse with all the pressure of the upcoming girls in Eteri's camp. She didn't magically acquire these problems by changing her geographical location.
Interestingly the judges still support her and give her huge scores, so arguably it doesn't even matter she's not with Eteri. Yes, the programs blow, but you wouldn't know it from the scores. So in a sense she is given a cushion, which she is smartly using to rework her skating.
