After deleting a scan station inside of Trimble Field Link, the colors connecting the stations changed to (in this instance) green to red/yellow

The color of the connections is based upon which scan in the group is considered the reference station.

In this instance, green was the color of scan station #1 and station #12 was red/yellow which became the reference station after scan station #1 was deleted. The color red/yellow indicated appeared as a warning or error when in reality it was just the color scheme.
