Hello. We've just encountered an issue where 3 jobs all assigned to the same agent for one stage seemed to complete, but remain active. The pipeline history did not show an icon for this stage - it was just missing. Go would not schedule any more runs for this pipeline. The agent which the jobs were assigned to had since successfully run other jobs for other pipelines. Restarting the agent and Go did not clear the issue. I had to click re-run for that stage to clear the error - it was not scheduling any new builds because the stage did not seem to be complete. I've attached a screenshot showing the invalid status of that stage (I had to manually construct the URL for that stage because the icon didn't appear on the history view).
