You Sir deserve an award. That is exactly what happened with a gear I created. I went to round every corner around the external edge and one corner would not round with every other corner. I ended up zooming in excessively and found that I had two anchor points almost on top of each other had to pass 8000% zoom to find that. deleted the suspect one which did not open a path to me(lucky guess).
This corner was created by layering a rounded rectangle behind a circles edge then using the shape builder tool to combine the overlapped section of the circle to the rounded rectangle and then deleted the rounded rectangle giving me one valley between teeth.
Does the fact the corner of the complex object being created by using the shape builder tool contribute to it?
