[uA24r838] Window Columns not being built

It is possible to make a wall or column from windows by replacing voxels with them. Lings will sometimes place the ladders correctly, but they won’t be able to place the windows.

Steps to reproduce:

  1. Create a column via voxel tool.
  2. Replace part of the column with Tall Stone Arrow Slits.
  3. Watch the building team fail miserably.

Expected Results:
Column is built properly.

Actual Results:
Nothing above the first window is placed. Sometimes the ladders are placed correctly, sometimes they are not.

Column is built properly if the cutter table is zeroed out (i.e. when voxels are not removed and the window is placed inside the wall). If there was a collision box type considered by the game to be a voxel slab this would not be a problem.
