The state of Mississippi sent the following update by email:
[State Health Physicists] investigated the inability to retract the source, and the RSO reported that corrosion inside the crank cables caused the cable to hang up. The crew followed their emergency procedures and called the RSO. The RSO retracted the source into the fully shielded position and OSL [optically stimulated luminescence] badges were processed showing that no over exposure occurred, and the occupation exposure limits were maintained in compliance.
