Furniture tweaks!

So far, I have been loving the game. Me and my friend have been playing it alot, one thing I'd like to suggest is for a way to lock furniture in position. We're making a bar in the cave, but stacking items is hard due to the floor not being leveled, everytime an item interacts with another, it gets bumped out of the way, or has physics applied to it again, even if dropped. Another is how the NPC's walk path take the furniture with them, it's been a bit frustrating. We're loving it though!
