What causes this error

A lesson references a building that has been deleted or renamed after the lesson was created. Since rooms are organised by building, this makes the lesson unschedulable.

How to fix it

  1. Restore the building — Go to the Buildings section and re-add the building.
  2. Update the lesson — Go to the Lessons section and update or clear the building reference on the affected lesson.
