Issues when transferring from Campaign to Mapping

My character has successfully completed Doriany Bossfight and talked to him after the fight, triggering the Event that is supposed to bring you into the post-campaign mapping hideout. I talked to both Alva and Doriani. However, it seems like a questflag has failed to load correctly, as when I ported to the hideout afterwards and wanted to enter my first map, it said "You can not access endgame content until you have completed the campaign."
I have tried relogging and restarting the game, both failed. When I tried relogging, it seemed to have loaded the Questflag for Act 3 Normal Post-Doriani, as the questlog told me to travel to cruel difficulty.
