hi, need some assistance from folks.. bit of a newb... lately my sonarr shows appear to be downloading successfully but the size of the file is way off. eg. nzbget says its a 2.8GB file when it gets moved to my final tv library the file is say only half or less than half the size of what nzbget has reported as downloaded. i can take the same file and then manually download it but this time not allowing nzbget to extract but choosing to do it myself manually and the file size is accurate. has anyone seen this, any suggestions of where to look for what the issue may be... i am running nzbget 17.1
