Just yesterday, I used your interior modules, which are also very nice! One thing, I noticed, though, is that there are no corners that contain windows (or maybe I just missed them?), which I found rather unfortunate. Consequently, windows can only be used on straight walls, which makes the rooms quite big. I also noticed, as I wanted to use the exterior as well as interior modules on one building, that the window is placed at different heights on the interior and exterior modules. It is no drastic difference and I doubt that any player notices (or cares), but I wanted to mention it anyway. Still, it is fantastic, how quickly you can build a complete house with these modules. Figuring out at what height to place the upper floor, so it fits the staircase, is also a bit tricky, but no big deal. It suffices that you know the height once, then you can simply take this value later on. I can post the height I used, this evening, if anyone is interested. Just as for the exterior I have to say say: Great work!
