Unbuildable Custom Building (With Error)

Hi there!
I’m trying to build a custom building, but wherever I try to build it, it always gets a red exclamation mark above it instantly and sometimes it gives me the following error message:

release-859 (x64)
stonehearth/components/building2/building.lua:776: attempt to index field 'building_job’ (a nil value)
stack traceback:
_ [C]: ?

_ stonehearth/components/building2/building.lua:776: in function <stonehearth/components/building2/building.lua:773>_
_ [C]: ?_
_ [C]: in function ‘update’_
_ radiant/modules/events.lua:59: in function 'update’
_ radiant/server.lua:66: in function <radiant/server.lua:63>_

This is the link to the house Im trying to build:

Hope someone can help me out.
Thanks :slight_smile:

The exclamation mark shows that the building is unable to be build (due to floating objects)
However, as said on discord im unable to solve it.

Hopefully Team Radiant comes to a solution
