Game Review Brilliant Changed ?

i always save my game which has a brilliant move at the special library. 

now i want to see my old brilliant game, but after click game review, it doesnt show as a brilliant anymore. im sure it was brilliant move before

here is the old screenshot of it

now the current screenshot of it :

what do you why this happen? i am sorry for the unnecessary question.

Oh it also based on rating? Hmm..

Yes as you see the old screenshot my rating was 857. Now my rating is 900±.

Stockfish constantly changes it's analysis of moves. I often find a problem where it says the move I played was only good, but a different move is best, so when I play that "best" move it only shows as excellent. It is probably because the depth of stockfish is simply not good enough in chess.com.

its still makes sense that the stockfish depth checking(or whatever it is) is changing anytime because maybe stockfish learn something new everyday.
but my suggestion to chess.com is atleast if a game is already reviewed, they keep it at their database the PGN so its not changed in the next day.
because if we wanna learn from our past game , we dont really sure that this move is really excellent or not in some condition

I think it's because stockfish updated and it doesn't count anymore??

I also found this on Google. A Brilliant move is when you find a good piece sacrifice. There are some other conditions, like you should not be in a bad position after a Brilliant move and you should not be completely winning even if you had not found the move.
