Delete the modded version, delete facebook, install the original version, start a new game, delete original version, install the 5.2.2 version of the mod, connect to Facebook, update to the latest mod version without deleting the 5.2.2 version
That's because your character has an item equiped that came out after 5.2.2, and therefore isn't in the game files for that version.
To fix this you need to log back into your account on the most recent version and unequip the item. To be safe, you should just wear the basic robes and one of the basic hairstyles.
