Short description of error
Confusing crown group error.
Exact steps for others to reproduce the error
Make a crown group and and move it to a non-visible layer. Try to use the crown group in the Tree Generator add-on toolbar, and it will give a confusing error difficult for end users to understand.
Request using a simple check to see if the crown group is on same layer and telling user "All layers with selected crown group need to be visible" if not.
