Another ubisoft game another weird online issue.

So basically after the latest Farcry 4 patch (It popped up at 17:00 today 21/11/14 when i started up Farcry 4)the game has asked me to link my UPLAY account, this suprised me as I had already linked my UPLAY account and have even unlocked one or two Farcry 4 UPLAY awards I was also able to jump straight into the action and play coop after meeting Hurk for the first time with no problems. So I entered my info and was told that my account did not exist. I have entered my info many times checking that it is correct but it will not accept that my account exists. I now find myself unable to play coop or multiplayer. A solution would be appreciated.

Something else I noted when playing single player after the patch was that the info on the map was all kinds of messed up with multiple examples of the same location/mission icon appearing on the map flickering and over writing other map information. So I am imagining Farcry 4 is having some issues...

As I said a quick solution would be greatly appreciated.
