Hey James,
It looks like the problem is still there. The exact exception is below but
I thought I'd pass along some diagnostic info first.
I downloaded the source, included it in our project and set some breakpoints
in SeparateSubclassVisitor.cs. When the SortByDistanceFrom method is called
with the providers parameter containing the mappings for the
ConstantColorSource and SubstringColorSource the parentType parameter is
null. That's where the null reference exception is coming from on line 104.
if (subclassType.IsTopLevel() && !(parentType.IsInterface &&
subclassType.HasInterface(parentType)))
continue;
The statement above references the IsInterface method of the parentType
parameter but it's null.
The exact exception is...
----> System.NullReferenceException : Object reference not set to an
instance of an object.

If there's anything else I can do let me know.
