I got kind of a special "bug" right here.
whenever I am in a group with the friend I am playing with or if he sends me an invite,
my security-system (which is Bullguard) tells me taht I have been "attacked" with a portscan by him
(at least bullguard detects his PC-username behind the scan),
scanning the ports "51164, 51501, 49826, 59787, 51467, 51473, 51477, 54567 and 51428". (as an example, the ports change every scan)
Bullguard then proceeds blocking the remote host for 5 minutes and as soon as the remote-host ip
(which is 25.129.150.159, a british IP and I guess the ubi-server then?) is unlocked, the same scan
appears.

I dont know if this is just Bullguard being overprotective, but I feel that no game should really make any security-system notify an alarm of some sort, so...

I dont know if its connected somehow or if it isnt, but while im in the party, sometimes I just get thrown out of an ai-match (and have to play against bots) and the game even crashed once.
