Another question: what happens when one builds a wonder and later removes it? Will the effects of the wonder go away then? I. e. Strategic Command (the only one I built so far): gives one general and five legions, do they disappear when I destroy the building? What happens when I use up the legions and destroy the building only then?
Does the Strategic Command have some more hidden effects? Because it would otherwise be useless after the general and the legions are lost in battle.
