Is it normal that I could build more than one merchant per city?
I think I found a bug. If you build a merchant or arcane lab, or science lab in a city and after you click the desired location you click 2-3 more empty building slots it will build MULTIPLE BUILDINGS OF THE SAME TYPE! I have several cities with 2-3 merchants and/or 2-3 arcane labs. The weird thing is that seems to be the ONLY WAY to build more than one of the same building type (except for huts of course).
