Can't delete orphaned download from Activity

Hi,
I have an orphaned Download in my Activity Queue that is long gone and removed from Nzbget.
When I try to remove it manually with the button “remove from download client” I get a warning, and the Download remains in the Activity-Queue. The Warning is as follows:

NzbDroneErrorPipeline API Error: NotFound
NzbDrone.Api.REST.NotFoundException: NotFound
at NzbDrone.Api.Queue.QueueActionModule.GetTrackedDownload (int) <0x000cc>
at NzbDrone.Api.Queue.QueueActionModule.Remove (int) <0x006e7>

Is there a way to remove this Activity?

thanks

Must still be in nzbget (or another download client), if you enable trace logging it will show everything thats coming back from nzbget every minute. Sonarr’s activity is built off of what it gets from the download client.

If you pastebin those trace logs and the nzb name we can take a look.
