I wouldn't try and move her now. Let her sleep and work out a strategy for tomorrow.
I posted recently as I thought that DS was dropping his nap (he's 2.1 too). However, I think that it was just a badly timed tantrum - he wanted another story before bed, I said no, gave him a kiss and left the room...which normally would have been fine but not on that day, he cried and cried and would not settle. That was the only day he missed his nap though.
Now, we just have to do a swift distraction after story and before putting him into bed. So, we tell him it's the last story, read it, then ask him what he's going to do that afternoon. Then while he's chatting about that, pop him into bed, kiss and leave.
It's a tiny thing, but it just seems to take his mind off the fact that he's being put into bed. Once he's there, he seems to remember that it's a nice place to be, and that he's tired and he happily drops off.
Personally, I'd move everything back as it was. You could also try a new dummy? Part of DS's trouble was that he's developed a new habit of chewing through his dummies so they are not as satisfying...
