[Bug] Can't place table inside thatch base

[Herr Morlock]

I have build a starter base, out of thatch with foundations at the ground (3x3) with walls (with windows) and roofs on it.
But I can't place the built table inside. Only on top of the roof...

The greenprint does not show up, when I try to place it inside. Propably because it shows ON TOP of it, since I could place it on the roof, normally, as I said.

Hm, now it works, after handling around with the mortar and changing from alignment to free placement mode. Maybe it's the Alignment mode what was creating those problems.
