Those of you worried about not having enough decos because of the aid button, keep in mind that the aid feature focuses on Specials, current age buildings (supplies, coin, and happiness) then current age decos. If you simply place decos from 1 or 2 ages below your current age and collect regularly from your supply & coin buildings, there shouldn't be an issue. The aid feature will only polish the lower age decos if there is nothing else left for it to do...
