My progress in multiplayer is not saved

[SemiSenior]

Hello, I'm having some issues with the savegame in multiplayer. Yesterday I've been playing 10h in multiplayer, I unlocked the golden cammo in 5 weapons. Today I logged in the multiplayer and discovered that all my progress from the yesterdays day just disapeared. Anyone can help me with this, or it's just better to dont play the game? Thanks.
