So I just happen to be looking at my sonar Wanted list and notice I was missing 3 new episodes of Adventure Time so I told sonar to look for them and it downloaded them and then I noticed I had already seen these and they were not new.
It turns out what happened is that S07E27-29 were changed to S08E01-03. So now I have files in my directory for S07E27-29 and S08E01-03.
I didn’t want to make an actual request yet, but it would be nice if:
We could be alerted when episode numbering changes happen during an update
We could scan for files that are outside of files known by sonar
