Hello,
It appears that i get resetted to my old prestige 3 lvl 26 while i was lvl 30 prestige 3.
It happend after when i used stat changer.
It happends everytime when i lets say shut off steam and then relog in and then in the start it gave me the error.
I used this changer https://www.mpgh.net/forum/616-call-d...ts-editor.html
And i changed only kills to 7580 deaths to 4500 and days and hours and minutes.
This is being discussed in that thread, some players get corrupt data, others don't
