Delete your ALL GAME DATA including updates & DLC.
DO NOT delete save data
Re-install the game - it should prompt an update to 2.03 = Accept & install.
On main game menu load Story mode, & in game buy something / ammo/medicine to save your game.
Now quit game & exit to PS3 menu.
Now go to PS Store & Re-download & install Animus 1.0 .
Then go back to Store & Re-download & install Animus 2.0 .
Then at the store Re-download/install COPERNICUS DLC.
Then start Story mode again - buy something & save again.- Quit to PS3 menu.
Finally Re-download & install The DAVINCI DLC.
Now start Multiplayer & activate Animus 3.0 in the options.
Once activated - Quit multiplayer & load your Story mode.
Everything should be on the map.
COPERNICUS symbol =(STAR symbol)
DAVINCI MISSIONS / Restored memories = (angel wings symbol)
I had similar problems with DLC & That's exactly what fixed it for me.
Now 100% Sync.
DO NOT delete Save data.
