NZBDrone failed SABnzbd download stuck at 100%

When SABnzbd fails (only failed attempts) a download, with for example an error like “Repair failed, not enough repair blocks”. The result from NZBDrone will simply be stuck at 100% and nothing happens any futher.

Drone Version : 2.0.0.1632
SAB Version : 0.7.18
Handle Downloads : On

This started happening after I updated both NZBDrone (stable branch) and SAB to above versions.

One solution is to revert back to drone factory.

This scenario has been discussed a couple of times on this forum.

But in these cases, log files are imperative.

Set log level to trace, wait a minute or so, then look into the log file. reason why drone refuses to import should be in there.
