BUG: Hardest puzzle= easiest puzzle???

cLxrr: a 958 rating puzzle. Mate in one.
XakmD: a 900 rating puzzle. 2 golds in head.
MTPgV:a 864 rating puzzle. Mate in 1. eifON: even a 600 rating puzzle appears!
But it appeared when I clicked the hardest level puzzle.
I am a 2200 rating player.

What the hell is that?

I have solved 30 puzzles in a minute and got 2 more points.
LOL.

Yup seems like a funny bug! Probably because there are very few members on lishogi?

@YoBot_v2
The rating is a cycle?
Where it begins, where it ends.
