You should probably add the full template even if irrelevant, or reports tend to get rejected. Also note the actual quest and cutscene number - from past reports I've tried to file, I'm not sure whether the people who deal with these reports actually "know" the game at a player level or can only check what you explain to them step-by-step.

I don't have access to the game right now to check the quest reference for the Unending Journey cutscene viewer, but for playing it via the MSQ it is the cutscene that plays upon exiting the Vault dungeon when you complete it for the first time.
