Looking in the support forum it appears the issue is Vuze using the torrent name in the metadata as folder instead of the releasename as the download folder and then Sonarr adding the torrent name it gets from Vuze to the downloadDir if the latter does not contain the first, and since in rarbg they are different (one ends with rarbg and the other with rarTV).
It appears it’s something that has already been reported ( Sonarr is not reading correct path from torrent downloads, works for some but not all ) but I have not found in the forums any way to fix it.
Any ideas?
