I'm having an issue using the corner tool with arcs. Whenever I apply the tool to an object containing an arc it doesn't catch the last vertex at the bottom of the arc and ends up going off at an angle. I've experienced this on a couple different models now.

Anyone else having issues with the arcs? Had a couple models where the tool can't catch the last vertex of the arc and ends up continuing at an angle not parallel to the rest of the model.
