Plutonium

I dont know what happend, I played yesterday, Tuesday 19 of april 2023, in the morning and i played several games, got a nuclear, got the sniper balista almost to the challenges after the one shot one kill kills and also almost complete the peacekepaer headshots, and got other few things. Then i played at the afternoon and everything normal, got another brutal and thats it. Today, Wednesday, 2:07 am, i entered to create some classes to enter the challenges and then i realized those clases were my previous ones, i have just almost 40 one shot one kills with the balista, also very far away from the challenges for the peacekeaper and i dont have the nuclear now, just 1 brutal. I don´t know what happend but is like i just lost all my progress from today, just today or maybe just from the time when i played in the morning got erased. i don´t know what to do but i like to get that progress bike, im pretty proud of that first nuclear and my classes and weapons, what can i do to get everything back?????
