Unfrotunately i cannot give two hearts

I believe I remember to have read it somewhere in this forum but cannot find it. Was that feature removed at some stage or was it more like a misudnerstanding from my side? The case I though  I understood is really: I build a warehouse or a tower or whatever building. This cost x amount of resources. when I don't need that building anymore I can destroy it and get x/2 (or some other fraction) of the original resources back.   Does anyone remember if this used to be the case and it was removed?

@Emacz, could you check out the site, see how it looks, and if I should change anything. Others are welcome to see it too 

Is this the ai doing it, or you? If it is ai, does it build houses in a row to the resource to speed the transportation?

Just was using ai to update our site. Do you think the nav bar (home, charts, civ) should go on the side, or the top, like it was?
