Where are the characters from the multiplayer? (Mass Effect 3)

I haven't run the masses for a long time, but today I decided to screw it up. as soon as the origin was launched, a bunch of achievements immediately fell, and most of the Persians from the cartoon (such as work, get, krogan voivode, etc.) disappeared, instead of them they were given to the disgrace of the usual.
Where did the coolest Persians go and is it possible to return them or open them anew?
