I just came back to my account after 2 hours and found all my rank ups and skill assessments from my last session were gone. I was rank 41, and now I am 40, with several weapon and skill kill assessments undone.

Happens alot this time of year.

There is something very wrong with the levelling system, a lot of ppl
are reporting problems including me. Lost retriever yesterday, and lost
quite a few assessments in the first month of playing.

Your ok, i had my modules reset. They were level 3, and then they were level 1 again.

k today i ranked 41 again and lost it as soon as I exited the game lost all assessments i unlocked

Maybe some cryfapper will tell you that this is a new feature of the game to improve the gameplay. Resetting stats to give more exciting to the game.

For the rest of us this is a terrible bug and we hope Crytek fix this asap.
It's a shame that a paid DLC was launched before fixing these things.

third times the charm! ^.^ just kept my rank 41
