It have been like this for over a year now. Started a lvl 60 character with the token and can’t play any main missons from vanilla. But i can ofc play all side quests except the Taris Bonus Mission. You start it and the waypoint updates on the map but not in game. Nothing happens when you click the npc.

u need to enable exploration missions on map. bonus series was turned into exploration missions in 4.0 i think it was - u cant see them unless u enable them. if u still wont be able to start the quest u mightve done it before - same thing happens on belsavis, balmorra and other places prob too - explorations missions are often visible right away - but they dont reset so if u finish them BEFORE you ever pick up or progress bonus series to that point u can get stuck because the quest is finished and u cant move forward.
