Description of issue: Processing show folders seems to loop endlessly. Debug log shows that the first show this happens to in my import folder is Biopunk. Sonarr shows it is processing folders but it won’t move on to the next show in the folder. In previous versions the import function wouldn’t tick the box beside Biopunk for example, and then it would move on to import the next show.
Also, if I cancel processing then start processing, Sonarr will not start processing.

Thanks for the info, turns out anything that has zero results will do that and Biopunk returns 0. We’ll get a fix out for that issue.
