Go back to the last time Autocrat worked. There should be a sheet and there will be a row for each merge job.
Once you have Autocrat working, duplicate the sheet as a backup. That will eliminate the need to search history.
I didn't write Autocrat. I just know a little about it. Autocrat reads the sheet, then deletes the sheet and at the end of the job writes the sheet again. The only thing that changes is some of the status columns.
If an Autocrat job should fail before the last step, you have the situation you are having.
I hope the above helps. If not, tell me where I have confused you.
