Moving a room on a flat surface cause a terrarin change

It looks like the block is raised on a foundation and when you moved it to the left it went flat on the ground. Did you try raising it back up again?

Also the stairs didn’t move, which is why the ground stayed raised. Did you try moving the stairs too?

Seems normal now that terrain can be manipulated. It would be nice if when moving a block the connected stairs also moved and it maintains its raise height and foundation though.
