10.9.8 Messes up Collections

[theguymadmax]

In the 10.9.z builds, a scheduled task runs at startup that removes items from collections and playlists that no longer exist. If your network drive isn't accessible at startup, this task will delete any linked items in the XML file. To address this, go to Dashboard -> Scheduled Tasks, find the “Clean up collections and playlists” task, and delete the “On application startup” trigger.
