Thank you so much for a timely response!
You are awesome in doing so and so talented. Not sure where you find the time.
Anyway, I will try to recreate the problem in Unity...then screenshot. Not sure how to explain it other than it doesn't want to slice tiles per the directions I've gotten elsewhere. Maybe it doesn't apply here.
I'll try the Theme_Sorter Again. When I have something or figure out what's wrong I'll post. Best to you.
