I recently upgraded from 4 to 5 and I am seeing some strange behavior out of SABNZbd (and NZBGet, but don't want to muddy the waters here). I have my config stored in /sharedfolders/AppData/SABNzbd and for some reason my downloads are now happening in /sharedfolders/AppData/SABNzbd/Downloads when they should be happening in /sharedfolders/Downloads. In the UI it says that the base folder is "/config" so I guess it isn't surprising. I tried to put in several other paths for the "Downloads" folder but the result was always a download in the /config path.
I thought I had a workable solution in place by creating a symlink to /sharedfolders/Downloads. This actually worked but the problem I have is that the app is still detecting an incorrect value for the amount of space I have left. This is another thing that is very curious - it detects that I only have about 10 gig of space left when all of my drives have waaaaaay more than that. Could it be detecting the OS drive?
I haven't tested it thoroughly but it appears to let me continue to download even after it thinks that I am out of space. EDIT - it did error out after a few minutes.
Anyway, here is my folder setup. Any thoughts as to what I could try next would be greatly appreciated.
