Hi, everyone!
I've just checked my rating graph and saw this.
Is it a normal codeforces bug or a browser bug or else?
Also, I found other rating graphs strange (someone taking part in a contest recently but had its rating graph updated until last year).
and i've been reloading it using Shift-F5 and it doesn't work either.
probably because of the zoom
afaik, its a (regular) bug that occurs during ratings rollback
