It can be a bit annoying when you want to set the current questline progress to a current progress, because you will have to type the complete-command for each prerequisite and for each prerequisite of each prerequisite etc. etc. etc.

My suggestion: Add an optional boolean value 'backtrack' to the bq_admin comlete command, which tells the mod to recursively complete each prerequisite and then the quest with the specified id.

I would try to programm this feature if you approve it.
