Complex roof creation created double wall

[Azuratte]

Summary:
I made a ridiculous roof and it broke the game, the hearthlings are still giving it their all though.
Steps to reproduce:

1. build this thing in the picture below

Expected Results:

no double wall

Actual Results:

double wall

Notes:
if you look in the 4 windows you can see a brick wall in them.
I will update this with the final result if the hearthings get through the build.

nice work on the multi roof function, had to learn you go top down though.

this is mid build. I’m, well I walk away and come back to much of nothing… I, I am not playing a game anymore, just playing a painting.

Holding out till the end, this is windows placed in the double wall situation. 2 of 6 being built, waiting on result.
