Reshape closed loop line feature

aretzler

I've been having difficulty reshaping line features that are closed loops (example: closed loop contour line of 950-ft elevation). The reshape tool seems to struggle if the portion of the closed loop that I'm reshaping passes over the loop closure (start/end vertices). Is there a workaround with using the Reshape tool to prevent this beyond just manually reshaping the closed loops myself with the Edit vertices tool? Thanks!
