Just started noticing my manual anime searches were failing with no results. Regular TV series were working fine.

Logs show:

Occasionally I also see this after the object reference error:

Feed does not contain application/x-nzb, found application/x-bittorrent, did you intend to add a Torznab indexer?

I went through indexer by indexer and narrowed it down to the two presets for AnimeTosho, both the Newznab and Torznab options cause the searches to fail and return no results. Disabling both indexers and Sonarr returns results as expected.

It seems AnimeTosho has changed something about their feed? I used to be able to get both usenet and torrent results from the same feed URL. I removed my old presets and re-added them fresh thinking maybe a URL had changed but nope, even added fresh they still fail.

Anyone else having this issue? Sorry for lame formatting, on mobile.

EDIT: So it isn't Tosho as I have discovered in the comments. it seems like v3 of sonnar doesn't like me having so many indexers returning so many results. It seems to choke up and time out displaying episode results if it gets to many results returned for processing in a timely manner.
