Inverted Slope Thatch Roof

Game mode: [Online | Singleplayer]
Problem: [Probable missing snap points]
Region: [America]

When you have a right angle made by two triangles the inverted slope roof does not want to snap into place.

Steps on how to reproduce issue:
0. assume you have come built a roof where this configuration is needed to finish closing the roof.

  1. start with a square ceiling
  2. add a triangle to the left and right sides of it
  3. add a triangle to one of the remaining sides
  4. from the triangle you just added add one to either side of the triangle.
  5. that should reproduce the bug when the ceilings are supported by a roof.
  6. ???
  7. Profit?
