Message 60066 - Posted: 11 Mar 2023 | 23:13:46 UTC - in response to Message 60065.

The person who had the task before you didn’t return it in the 5 day deadline. Then it was sent to you. Then you started processing. Then the person before you returned it. When you returned it you also get credit as long as you return it within 24hrs of the first result. If you hadn’t started processing on your host when the previous host returned, then the server would have instructed your host to cancel it. The timing of events tells the story clearly.

It happens. Not necessarily common, but totally makes sense given the timing of events, and it’s happened many times before.
