Well I have no idea what on earth is going on. For some reason, All of my original sab and sickbeard files have just randomly popped up again on my shared drive under SNAP. I deleted the shared name folder via MC and rebooted. It almost looked like a newer "Applications" folder was created on top of the old one. When i deleted the "Applications" folder the old one reappeared. That just makes no sense to me at all.
I was originally using the plugin before my files mysteriously vanished and then i switched over to unmenu to see if there was an issue with the plugins. Unmenu packages still seem to overwrite the original folder even when placed outside the shared name and just being directly on the disk itself on /mnt/disk (that is still being mounted by SNAP). Although by the feel of it and with my files popping back up from the dead, It's probably not an unmenu package installation error, my unraid just seems to be full of ghosts.
Ok, I've now installed both sickbeard and sabnzbd via unmenu package and pointed them to my existing installation folders. So far everything seems to be working. I will let sab grab some files just to make sure and then shutdown to see if it's still happy.
I am totally at a loss for words, I have no idea what on earth just happened. Thanks for the reply though
