Losing Latin Honors in the most tragic and heartbreaking way possible

I've been taking additional language classes P/NP on the side for the past few years for fun, and the only reason I'm not auditing these classes is because it's not allowed (single digit class size).

This quarter I received a letter grade instead of P/NP and my GPA tanked from a 3.98 to a 3.92, completely losing Latin Honors, and I genuinely don't know if this my fault or not because my professor has told me that a few other students are also experiencing this happen this year, which is something that's never happened before even once in their time here.

They've told me it's truly out of their hands despite sympathizing with me. It's feels even worse because I did good enough to skip my final so I could focus on my other classes, and could've earned a better grade had I known I wasn't P/NP.

I already submitted a petition to late change my grading basis, but was denied as it seems they're quite strict on this and require concrete evidence of an administrative error, which I simply don't have.

I'm premed and I know it probably isn't as big of a deal as it feels, but it feels like shit to have spent years doing a relatively hard major (biochem), and to have spent all that time and effort maintaining my GPA throughout my major classes, only for it to just get fucked from either a single click or admin mistake that I can't change.

If anyone has any advice please let me know.
