[Error: Missing Job 13 when trying to move from active to completed]

Created by: ghost

I have a cleanup job running every 5 minutes. This is all it does:

return Promise.all([
    this.queue.clean(0, 'completed'),
    this.queue.clean(0, 'failed')
]);

I don't have any other code that could possibly remove jobs. I'm running master because of that leak you fixed. Concurrency is 4.

Any idea what could be causing this error? If it doesn't look like I'm doing something wrong with clean I can try to isolate a test case.
