Same here, can play for 5-10 min and then it crashes even if just chilling in the settings menu.
And then it says it fails to synch cloud saves

My update is finished and the game is back to 1.3.1 and my saves are restored and no longer corrupted.

But I tested closing the game and restarting uplay. And then it started downloading 1.3.0 again

PC
Yes I played on TU 1.3.1 yesterday
Yes the game "re-updated" today
My last save was yesterday 7 september at 11.30pm
All my saves was corrupted
Cant send image because now the game is updating to 1.3.1 again I think

I verified game files and restarted Uplay, so the game started a download. Will check save files status when it's done

Same problem for me. I played yesterday after downloading 1.3.1 and everything worked fine. Now this morning I had a new 12gb patch to download and after that all my saves are corrupted. I play on PC
