Yep, the game has been crashing a lot since TU 12 but yesterday got worse, it just reached the pinnacle of the incompetence of massive, the game is in absolute abandonment and just unplayable.
The game has been running fine for me the last 20 mins (EU server, PC). I didn't notice any UBI Connect or game updates so it's probably a server side issue and the fix will be deployed worldwide in a matter of minutes, depending on region/platform.
