Personal Fractal level not advancing
That screenshot isn’t sufficient to demonstrate a bug. My regular crew of fractallers includes several who have done many >L40 fractals and still have a personal level much less than L40. That’s because your P-level can only increase +1 at a time, regardless of whether you do your level or 10, 20, or 50 levels higher.
Thus, it’s easily possible you got credit for 52-56 before you were at L51 personal level.
To be sure there’s a bug, you’d have to know the sequence in which you did them.
tl;dr did you do the L52+ fractals before your p-level was 51? f so, then there’s no bug. If not, then contact support and provide them with the approximate dates, so they can get to the root cause.
