I've written a house mod where I have a placed a "FarmhouseSmith01" and an NPC that goes out of the builiding every morning and goes to the forge. She keeps faling through the boardwalk that is part of that house. I've tried placing the exit marker a litlle abouve the boarwalk en I've tried placing the navmesch a little above the boardwalk but niether do the tric.

When she returns to the house in de eavning she walks across the boardwalk to the door with no problem.

Whatelse can I do to fix this?
