The queue has actually been empty for awhile. It looks like that sighting is stuck and is keeping a very strange number (there haven’t been 19,000 jobs total since the machine learning server started). We’ll work to push it through.
@PiiaMutka - there was some blocking of the queue, and i believe i have fixed the situation now. the sighting you link to is now showing proper detection results and can be processed further now.
if you notice other sightings which also seem to show they are behind in the queue still, please let us know.
