SCN 2818 introduced an OpenLoop press to the Tube Mil code. The intent was that controller would stop processing punch targets while the Run Cycle Shear code was active and pick back up after the Shear was completed. This preserves the punch queue targets in case an operator is holding the Manual Shear input ON, attempting to disable shearing.

The code that was supposed to disable the punch target processing had a flaw in the logic and punches were still being processed. This resulted in more parts than nessesary having missed punches after the Manual Shear was complete.
