Prompt for Save during Sync

Is there an explanation for why I should be prompted to save a database during sync? The exact circumstances were: DTPO was left running overnight with a couple of databases open. When navigating to DTPO in the morning it was open with a Save panel for a database that ASAIK had not been open, but was assigned a daily sync at 7am. I responded yes to the Save prompt and gave it a different location, it saved the database and completed the sync. I now have what look to be two identical copies of that database. Any clues as to what happened?

Hmm. That’d be a bug, please open a support ticket, if you would be so kind, so I can track it down.
