I have resigned myself to not being able to finish the core game personal story on this account due to the same bug disconnecting me on a dozen occasions at least. I progress through Forging The Pact until the cutscene with the necromancer at the end. The audio will then cut out, the cutscene will play out without sound to the end and afterwards the game thinks i'm still in a cutscene and then dc me. I then have to try to redo the whole story chapter, at which point the same thing happens again and again. At the end of the living world season 3 story (Frozen Out) quest, during the ongoing conversation at the end of the quest, i get constantly disconnected at roughly the same point in the conversation. Only Once has the game progressed to the cutscene of Braham shooting the arrow at Jormag's tooth, at which point the cutscene ends, and the game thinks i'm still in the cutscene and then dc's me, and makes me do the whole 20 minute story chapter again. I've attempted to do this 6 times now, and i'm tired of wasting time trying to progress this story. (Yes i know i could just go to the journal to start episode 4, but i want to do this in order fully).
Please investigate and sort this issue out, as i'm sure that it's not the first time someone has mentioned this
