Endgame citadel still shit

just wasted my time working on chopper citadel that they always "INTENTIONALLY" make it circle around to go there. just kill the faridun boss but got disconnected without even loot it, connected and try to go there but can't go to the boss room, what a piece of shit, fix your trash endgame, your race event is just a bullshit, and stone citadel still cannot complete even after kill the boss. I'm so pissed with this bullshit.
