EDIT: Yep, it was using control to place the initial cornerstone.. Warning to everyone else not to do this!
It's going to be a major pain to destroy that wood wall for a 20 phlegm noob.. sigh
Looks like it's going to block all the way along.

I've attached a picture....
I can't extend this stone wall south any further...
The menu comes up but whenever I choose "Extend South" my avatar just walks up to the wall and stops. There's no error, and the construction site never appears.
It's totally flat there...
What he heck is going on???
