Media File Path loops
I've observed over time, in different projects, different premiere versions and on different Macs how sometimes the browser column for Media File Path specifies a path that doesn't exist. It starts off fine at the root, ends up fine, but in the middle there can be added several loops taking the path through other folders that really doesn't belong to the path. I call this Media File Path looping, or Ghost Paths.
Below, there is two items from my browser that in the osx file system have similar paths. The first is correct, the second has the extra loops through other folders marked in the red box. To be clear: The path in the second example does simply not exist on the computer drive file system.

The file, video or audio, will play in premiere, so the first noticeable effect of this loop is when you try to use "reveal in finder". Then you will be taken to the point of the false loop, where the finder system will give up to find the actual file you were asking about. You can still find the file manually in the system, if you know where to look.
I strongly suspect, even if the media plays, it also has a "confusing" effect on the performance of the system, so when I see this behaviour, I use some time to fix the paths. Relinking works, if you take the time to manually override the automatic pathfinder, and specify the actual folder. When there is a loop in the Media File Path, you will only be taken to the first wrong node of the path.
I'm not sure why and when this looping occure. Importing? Have not seen it. Batch relinking? Maybe. Reconnecting drives that has been disconnected? Plausible.
All I know for sure is when the wrong link is established, it's persistent through closing program, turning off computer, trashing prefs and all that. I would appreciate other experiences and observations of this phenomenon.
