TBSS Affecting NMDA

In the ALY case, a TBSS adjacent to a weak hook caused the NMDA marker to be displaced south of the meso. On the next scan, once there was a space between the hook and the TBSS, the marker jumped back north to the correct position, co-located with the NTDA marker. The NMDA ID remained consistent even with this jump.
