Yeah I am out of unique titles, so I will use generic ones from now on ^^.
Anyway, you will have to wait for another week or so until the next version is released. Implementing real buildings with several floors is much trickier than I initially thought. The game wasn't programmed to handle this feature in the first place and as a result I am forced to alter / rewrite large parts of both the general and the AI code. Moreover, adding optional floors to buildings raises several critical performance issues in such a NPC heavy game. I have some ideas to alleviate the additional processing power required but testing those ideas takes time. I will keep you posted.
