I placed 54 among rated participants in the recent EDU 166 round. With a delta of +121, I reached 2127 points of rating. However, if you open my profile, it still displays the rank of Candidate Master, and my username is still shown in purple. This makes me believe that, along with the other people affected by this bug, we might be some of the strongest CMs of all time.
TL;DR: I have not been granted the rank of Master. This is outrageous. It's unfair.
