I've re-run the superpmi leg in my PR today and it has failed in the "Publish SuperPMI logs" and "Publish SuperPMI build logs" with errors:
##[error]Artifact SuperPMI_Logs_x64_checked already exists for build 58267.
and
##[error]Artifact SuperPMI_BuildLogs_x64_checked already exists for build 58267.
It sounds like a bug.
