@Serious_Python You have cloud saves and local saves. If they mismatch, which most often happens if you're playing on a different machine or if you've done something with your local saves (moved them, used a save editor, played offline, not allowed/waited for the cloud upload before closing Origin, etc), when you start the game the Origin client will ask you to sync them, you can choose to either use cloud data or local data, whichever one you choose will overwrite the other, and any lost data is not recoverable unless you have backups, EA can't get lost/overwritten cloud data back.
It is, unfortunately, way too easy to mistakenly select the wrong option to sync and lose a lot of progress, which is why whenever I get that message I backup my local saves and pay close attention to the dates and times for the local/cloud saves it wants to sync before making a choice.
Sorry there's not better news ☹️ Totally sucks to have lost so much progress. Also seems weird that either your cloud or local data was a year out of data.
