Lost Progress on Vanguard Class

Hello, I was playing operations in space marine 2 yesterday trying to level up my vanguard class and the melta. I ended up gaining a few levels and upgraded my melta to the next rarity along with the combat knife, as well as completing a good number of ordeals. When logging in today all of that progress was lost and all of my class customizations were also reset. Is there anyway I can get that back? It took awhile to grind those weapons and it’s a little intimidating to do it all over again. I appreciate anything that could help, thank you.
