Hi, I have been playing TDU for ages now and I play it along with my two sons. We have recently had a problem when trying to add one another to our friends lists. When we click add to friends list, nothing happens for either of us and when we select friends on the map menu, neither of our chars are viewable to either of us there, but when we select all players on the map menu our cars are there. We have tried several times to add one another to our friends lists but it just isnt working. I just wondered if anyone else has had this issue and if there was a way to overcome it. Thanks
