I think this might be a bug but since I'm so new to FlexGet I wanted to post this here before submitting a bug just in case I'm just ignorant on how this works.
So, as the title suggests, renaming is failing even though the main video file in the torrent is clearly greater than 90% of the whole torrent.
2018-04-26 20:13 WARNING deluge Download-TV No files in "Riverdale.US.S02E19.HDTV.x264-SVA" are > 90% of content size, no files renamed.
The file is 183.8mb's and the only other two files in there are 0.1kb.
Confirmed with another torrent. This isn't a one off behavior.
