Phoenix world crashed during the instance during 5.55 quest Death Unto Dawn. It counted the instance as completed, but presumably because the cutscene comes as soon as the instance completes, the quest has already moved on and I have no other context.

I don't particularly want to progress any further like this, but seems I have no choice as the GM team say they can't reset quest progress, but this could have been avoided if all quests were abandonable. Or at least make cutscenes available in the Unending Journey BEFORE you complete the quest - my only option now if I don't want to be confused or spoiled is to skip the remainder of Death Unto Dawn and NG+ the last half of post Shb, which is very excessive. GM suggests NG+ is unneeded and to watch the cutscene in the Unending Journey, but I still have to complete the rest of the quest (which I have no context for) first.

I'll do NG+ later but it's honestly a shame 5.55 had to be ruined like this, it was completely avoidable. I understand it's rare, but if issues like this can happen then there must be a way to reverse it.
