Is the editor included in the steam download?

[City Builder]

I've also revalidated Crossworlds and while it does always find 1 file that fails validation it doesn't add that option to the tools menu or to the right click menu.

I have to wonder why you can see that and we can't other than perhaps permissions are not set properly and maybe it only goes out to the developers or publishers of crossworlds maybe. Or something else entirely I suppose. All I know for certain is that it's not showing up on our steam clients at the moment.
