I've had the same a few days now and I am having a hard time playing. Only 2 out of the 5 friends I have is showing up on ESO not only that but when we group up enemies are invisible. Also I have an issue with the combat where enemies are hitting me with with a melee attack from a far distance and I have the game clips to prove it, also have an issue with quests not being available and just stops and shows nothing else to do or nowhere to go.
