Unofficial Skyrim Legendary Edition Patch

There is apparently supposed to be another flashback scene just as you get to the last room in the Avanchnzel Boilery, but it doesn't trigger properly. The trigger for it is in the corner just before the room. I only noticed it because the scene npc's can be seen to glow briefly and disappear as soon as you can see them. It's much clearer if you use tcl and avoid the corner entirely, as they're all just standing in place.
