[New Builder] Layer error

Trying out the new builder, but when placing items or roof, it doesn’t lock to the layer you are building on

Steps to reproduce:

  1. Create a building with multiple layers
  2. Select layer
  3. Place object or similar to layer
  4. The layer doesn’t lock, so if pointer hovers over where another layer will be, will go to new layer, happens if you place roof first

Expected Results:
Will stayed locked on the selected layer.

Actual Results:
Moves to the layer where the pointer is pointing.

Will try replicating whilst not changing wall heights.
