This result had 3rd replicant issued 16 minutes after originals sent.
Mine was the _0 aborted which is why I looked.
Edited to add info on other tasks on same PC from same request.
2 other WU show same 3rd replicant, possibly related to 2 WUs where 2nd replicant sent at similar time, both detached for some reason.
