Often maps have lots of civ structures to be garrisoned. After those being destructed, in place appears a pile of indestructible rubble. That garbage blocks the passage for units, yet the only way to get rid of it is to start constructing something super-close to the rubble - somehow scaffold erases those leftovers.
Just like anything in Generals civ structures ought to have same INI parameters, but i fail to find where those rubbles are created. At best i'd wish them either not created at all, or self-destruct after some time.
May somebody know how/where proper code parts are?
