Refine mesh mask problematic vertices

[zhongjiedong]

What is it that you want to do that isn't currently possible?

When you try and refine mesh, sometimes you get an error but it doesnt show you which vertices that are problematic

A feature like this would be a LIFESAVER! I've been dealing with problematic vertices and essentially just blindly masking in decreasing intervals until something works.
