One of my coworkers ran into an interesting problem. When he opened his local file, about 10 fire protection elements (sprinkler piping, heads, and equipment) were being borrowed by default. He could not relinquish the elements by saving to central or clicking relinquish all mine. Since he was always borrowing these elements nobody else can open there local file. He deleted these elements and the problem went away, but we are still confused to why this was happening.
