You said here that the player's collision box would also be smaller if your mod is active. This may be natural, but now I can squeeze between a wall and a cliff where no other wall can be set. Also, I can walk on and off a patch of land surrounded by cliffs on all sides. Here is a link to a short video clip displaying this: https://forums.factorio.com/download/file.php?id=44694.
Could you do anything about it, or is it impossible? If so, will it really be only Mini-me that can do that or must I be concerned that biters can storm the cliffs?
