Critical start times inconsistent

The values for critical start time in the chain of jobs in the critical network appears to be inconsistent. There are predecessor jobs that have critical start dates that are later than their successors.

Cause and solution:

This inconsistency occurs when critical start times are recalculated after some of the jobs in the critical network have completed. To optimize the calculation, new critical start times are only recalculated and updated for jobs that have not yet completed. The completed jobs retain the original critical start time. If a completed job is subsequently selected to be rerun, its critical start date will be recalculated.
