Calculations out of date - indicates that changes have been made to the selected alignment. Cross sections and volumes need to be recalculated (see also Recalculate All dialog).
Cost out of date - indicates that changes have been made to the selected alignment that has rendered the costs out of date. Out of date costs may also effect mass haul quantities if OptiHaul volumes are used (see also Mass Haul Options).
Dependencies are out of order - indicates a dependent aligment is processed (in the alignment list) after the alignment which depends on it. For example, Alignment A depends on Alignment B, but B is processed after A. (see alsoReference Features).
Circular dependencies - indicates that alignments are dependent on each other. For example alignment A depends on B and alignment B depends on A. (see alsoReference Features).
Reference alignments missing - indicates that dependent alignments are missing. (see also Reference Features).
