oh no I totally agree, what I meant was for her to completely flip 180 as the OP describes it is lower on my list. Most of the time if the tack is becoming uncomfortable you don't see such sudden changes. BUT yes absolutely rule out that the tack is still fitting properly and not causing pain. I definitely think she hurts somewhere, but I'd be more concerned about about something like teeth or an injury first. But yes, sorry I didn't mean it couldn't be the tack, I just meant it shouldn't be the tack.
