I've had that happen before, where it doesn't appear to work (so I spam it of course) and then see that it hasn't moved, save it, and then reopen, only to find that it HAS moved crap but the window wasn't updating for some reason and the model is irreversibly screwed.

Course, I've only done that ONCE (learned my lesson) and that may not be the case, but try it, since the model doesn't look too far along there, and see what happens.
