think thats something that needs to have the server upgraded. which planet, kirb?
(and what does *getvers show for it?)
Far as im aware, this'll disappear as long as the server is 1.42.2 or higher
in which case that may well be a feature :] (i have vague memories of adding a capacity limit in for buildings.. um.. but now that i think of it.. did i? um.. hedge? what have i done? :] )
