Appreciate the feedback WoodWoseWulf.

I'll bear that in mind moving forward.

Yep - that strange square in the middle of the National Park is Dillon's Farm. It's what I thought I had labelled, but I must have labelled what was outside of the poly rather than what was inside of it. {facepalm}

It certainly is a small world. I only knew about Dillon's Farm as I attended a firecall there a couple of years ago.

Sure, if you can fix my mistake, I'd appreciate it.
It was only the cleared/grassland area which should be marked as "Dillon's Farm".
