1.) Change the 'state' of a 'reference drawing' to 'released', but not the parent drawing.
2.) Change the 'state' back to 'work in progress'.
3.) Now try to 'release' the 'parent drawing' and include the children.
The reference drawing that was released, then set back to work in progress, will show in the 'change state' dialog as 'released'. There seems to be no way to get it to re-sync to its actual 'state' of work in progress.
