The Dink Network

I'm creating a dmod & I don't know why hes walking though the buildings. I have them set as hard people/creature as do I everything else & it's working for everything but the buildings. He won't stop walking through the buildings. What am I missing here? Can anyone help?

The hardbox usually isn't adequate to keep Dink off the buildings, so you need to stamp hardness tiles around it...

I believe there is a program called 'Hardboxer' that surrounds the buildings with hardness as well, which fixes this problem also.
