Helpful video, thanks.
Maybe a silly question, but would buffering the entire layer with 0 not be an easier solution? What would be the downside of that?

Hi Jacob

Could you kindly help me out here. My invalid output attribute table is empty. How do I fix that?

[lukemiller]

Thank you for the video. When I buffer my invalid layer, the buffer doesnt cover the entire invalid layer extent. Any reason for this? how can I troubleshoot this issue?
