We'll need the docudemons more precisely, to know what exact options are available for those buildings. There seems to be nowhere to specify scope in the commands as they're used, but as you are aware there's a 'true' statement, and it's curious what that refers to.

Anyhow, but possibly unrelated, levy scripts are exceptionally easy now.

EDIT: also, I'm not entirely clear how destroy_units works, since it seems to refer to a label and regular (non named char) units don't seem to have labels.
