This is it. The game crashes whenever a session is finished with a bug report message. I asked some of my friends and everyone has this problem. Could be related to the latest Uplay update, I don't know. Ubisoft, ACIII community begs you to fix this as soon as possible.
Update: This could help you.
It seems everyone in ACIII community is facing the same issue of crashing and missing friend list since the new uplay update was on roll. And UBISOFT seems reluctant to make a fix. One of my friend had already raised a ticket at support but UBISOFT responded with some infelicitous and junk stuff. I strongly urge UBISOFT to take the matter seriously and make things right ASAP. You don't wanna loose your valuable players UBISOFT i hope.![]()
