Put the summary of the bug you're having here
What I expected to happen was...:
was that the chest were going to connect and the blocks like slabs and stair will be transparent
What actually happened was...:
the stair and slabs are dark with lava or light behind it, and the chests are not connecting together, also the chests are like MCPE
Chests connect to what they're placed on when shift clicking, and only connect to same direction-facing chests.
Already reported.
