Version 0.7.5
Made some test walls with inside corners so the walls would be drawn on the outside of the path and had two problems:
I expected the gypsum to be on the inside and the sheathing to be on the outside. This is what I got with the gypsum not only not on the inside, but buried in the 2x4:

And the corners are offset so they did not meet.

Note also that the wood has no texture even though the Auto Assign Materials was set to "Yes".
With the blizzard of inputs, I've probably set more than one thing wrong, but have no idea what.
