Uhm... I am a little confused here.
Do you mean that by some reason the amount of won races have decreased?

won the race, which reduces the amount of reasons.

When was the time you had 2850 wins?
I think if you contact Victor (developer) either by PM or this link: https://www.lfs.net/?page=mailus
I'm sure they can provide help.
