Before the contest "TypeDB Forces 2023" my rating is 2180, but I did not perform well in this contest, so my rating deducted 102 and became 2078, candidate master.

After that, I registered codeforces round # 848 as a candidate master, but due to the rollback reasons, I find the status of my account became "out of competition" during the round. I thought that is only a temporary bug and after rating is fixed, it will not affect my real rating. And in this contest, I got my best rank ever (if rated, rank 11th in Div.2) and I could have improved my highest rating.

But today I am sad to find that I'm only rated for the "TypeDB Forces 2023", but got unrated in round #848! :(

If rating can still be modified, MikeMirzayanov please help me restore the correct rating for round #848, it's really important to me.

I participated in ABC 250 last night, and there is something really makes me sad.

I didn't solve the problem G and problem Ex, but after the contest someone told me these two problems are exactly the same as two previous problems on Codeforces.

Let's compare:

ABC250G and CF865D

ABC250Ex and CF1253F

And recently I often hear others talking about ABC that has a lot of problems are exactly the same as some old problems on Codeforces or other platforms.

Is this normal and fair enough? I know the meaning of ABC may be more educational, but it's still quite sad to hear someone say some words like ‘I find the same problem on Codeforces and got AC by learning the solution during the contest’ .

Sorry for bothering.
