Issue:
Gantt Insert/Update Errors popup when trying to save a status change (IE from Started to Completed) for certain tasks. If you attempt to change the status of the task(s) from the task itself, the change doesn't save. 
Cause:
The can happen if there is any ETC left on the task that is attempted to be marked completed, as the ETC must first be cleared on the task before closing it. 
Resolution:
Change the ETC for the task to 0, then you can update the task status to Completed.
