[new_builder] Moving walls down is strange

Two adjacent rooms and a third on top of them. When moving walls of one of the 1st floor rooms down, the whole 2nd floor moves down with it. Is it intentional?

Steps to reproduce:

  1. Build a following building: two rooms at ground level, 1 room on top of them. Rooms at 1st floor share a wall.
  2. Try to reduce height of walls of one of the rooms downstairs (doubleclick and pull down)
  3. The room upstairs moves down with them. Also, walls of the second room downstairs break.

Expected Results:

  1. Selected walls of the room go down
  2. Shared wall stays the same
  3. 2nd floor stays the same

Walls selected:

Moving down… boom.

  1. happens ONLY when you have top room and bottom room walls sharing coordinates. In other words, when at least 1 wall block of the 2nd floor room is directly above the wall block of the room you’re changing.
  2. If the walls for the room downstairs were lowered before 2nd floor room is added, it is not influenced by further deformations. In other words, the room below must touch the room above, otherwise this bug doesn’t show.
