Long time MC user here. Thanks for the great product. I primarily use the Windows version and I'm running V31 there, but I still use V28 on my Mac.
I have Auto-Import set to monitor 2 network-shared drives, and each time I re-open MC and auto-import runs in the background, it creates duplicate versions or listings of the same files. The longer I let it run in the background, the more duplicates appear in my library. My point is, the duplicates do not appear all at once...they accumulate over time which makes me think it has to do with background auto-import activity. See attached screenshot for examples and my auto import settings.
The problem described here has occurred on previous MC versions for Mac, but never on any MC version on my Windows setup (which monitors the same network-shared drives).
I'm not sure I've ever left it open long enough to let the auto-import run to completion in the background (is there any way to check on background auto-importing activity?). My library's very large so it takes days. I'll leave it open for the next few days and see if the problem fixes itself,
Other than that, any ideas? Is this an issue anyone has reported before? Thanks in advance.
