For what it is worth I was on for 8-10 hours yesterday and did not freeze, but I did not download the new connect because I leave the program running just log out, so it looks like it is a combination of connect and server.
same for me, i played yesterday the whole evening. logged in in the morning and left my pc running during work, no issues, but with todays ubisoft connect updates the game is unplayable, every 2-3 mins game freezes to death.
uplay just patched but game still crashes out. Golden bullet is easiest one of the best events, it's my favourite and i'm going to miss it at this rate((
and still not fixed, also those saying "ubi connect is not the issue, I installed an old version and it still crashed". it auto updates on startup... you don't have an older version, because as soon as it starts it updates to this version that is broken.
