Final area on main plateau not available for expansion

[carousel32]

I've cleared all the areas on the main plateau but one. When I click Expand it opens up areas on the other levels but not the last one on main. I don't want one little spot covered in trees and rocks. What's up?

This area cannot be cleared.

Thanks for the feedback. For corner and ledge areas it's totally not a simple fix like you suggest. For some of the seemingly random areas, we actually reserve those spots in case we want to add new on-board things (like the Dawn Tree) in future updates. Basically, if we let people expand everywhere, if we ever wanted to add a new thing to everyone's boards, we couldn't, because players would have built on those spots. That's only a few small spots though, 5 or 6 I think.
