About object placement, I thought it was intended due to some internal mechanism since the ancient 16*16 / 32*32 update, but now I think about it, a few weeks ago when I started scripting new doors I had to edit the model's offset because newly placed doors weren't aligned with the walls. The problem probably appeared one or two months ago, while I was mostly building and not scripting, so I didn't it notice earlier. Indeed, making chests a single object would be handy, especially for setting up scripts. That's great, thanks :)
