Medical room conection to other blocks
The medical rook, despite beeing a large block with a large surface area, seems to only connect to the blocks under it where it has its conveyor port.
The rest of the surface does not connect to other blocks. When you delete the conveyor , the whole medical room is free to float off.
I found this out the hard way when i got hit in the junction and lost the whole med room, so i went in creative to test it.
I did not test what would happen if there were blocks above it too.
