cba to make an account, but you could add:
Automaton Horses - Justified, given that the horses in this game are little plastic figures which don't even have joints
Everything Fades - Averted if you have an add-on that makes players leave behind a body on death. Yes, it can obstruct hallways. More often than not it seems like the server host has to be online so he can clear the bodies every once in a while.
Floating Platforms - Although the game's building system requires everything to be linked to the ground, that's about as far as that goes - you can make entire buildings supported by a one by one pole. Of course, some modders have come up with ways to completely bypass this system and make actual floating bricks.
