Roofs

[RaginCajun]

So my first world I didn't notice any issues with roofing.  Since the last patch on my new world it seems they do not build roofs.

Rooms are 10x10 typically or smaller (bedrooms are 5x5).  Any larger rooms I've put additional walls inside (like a pillar support) but this doesn't generator wall building.  I'm also building off of existing rock walls in some cases (not all) but this doesn't seem to matter as they are not roofing either section.

Help?
