Last Light Inn has two quest-outcome objects not working properly;
If Isobel is saved from Marcus; she will respectfully bury Marcus the next long rest. However although he does get a grave marker, he doesn't get an actual grave so his corpse is left out in the open (and makes Isobel look like she just tossed his corpse over the balcony instead)
When the prisoners from Moonrise Towers are rescued using the boat behind the walls; the next long rest the boat will end up on the roof, its seats will end up floating by the side of the inn, and the ropes will be floating where the boat originally docked.
The Harpers certainly beat the Patch #4 Duergar when it comes to parking their boats
