Anyone figure out how to get the key in the tree during "The Rescue"?

[Grim]

During the Ragnarok quest "The Rescue", there's a locked building behind the large building (with the quest marker on the door). To the left of the locked building is a tree with the key... You cannot climb the tree. There's no way to jump to the branch with the key (no building that's tall enough/close enough). There's a door to the building that's barred, but there's no openings that allow you to destroy the bar.

NOTE: I don't know if we maybe revisit this area later and are suddenly able to access the key.

use the ability Incendiary Powder Trap to get through barred doors

There's a moveable box on rails, pull it upto the tree and climb on top.

Good to know this still works (i.e. didn't get patched out). Unfortunately, i just don't have this skill (started this quest shortly after getting to England, which was probably too soon)

Didn't see a moveable box, let alone rails. The path to get anything to the tree seems very limited because of the hay. To clarify, we're both talking the Ragnarok "The Rescue" quest?

It can take up to 15 arrows to explode the barred door, but it always works
