Yeah it was supposed to be the same side of tbe same door, sadly some inconsistencies are present
...But do you think they are obvious enough?
First of all the ceiling is not inconsistent, its just different as the area the door takes you to gets closer the the bedrock cave style dungeon entrance, while the corridor is built with stone slabs.
The floor tiling is indeed inconsistent, but come on, its barely noticeable that the tiles are perfectly aligned in one and shifted in the other..i could fix that.
These are both sides of the same room, because on the other sode of the door its something else
