yeah, the placing is wierd.. you can create an advanced buildings spell, meaning the spellbook, and add "tiny building" ability to place buildings.. would look normal and work properly.. the only problem I noticed is, that you can't use it more than once, else there'll be some problems with the buildings, wether the cooldown of all buildings/abilites start, or you can only place the same building, the spells don't like each other.. dunno if this is fixable, so the only opportunity I can think of now, is using some other ability that needs a target, just remove all effects of it, and trigger the building, like check money, and then place it at position of target..
