I've had it multiple times by now that comfy runs for like 5-15 min after I shut off my screens and then return hours later only for nothing to have happened in the mean time and then suddenly as I turn on my screens to check progress that the queue starts again 1-2 min later only for it not to have generated a single image in the time I was not there, very strange behaviour.
