Favorites in sidebar keep disappearing
I'm running an iMac with Sierra 10.12.3. The favorites I've created in the sidebar which link to folders on my external hard drive keep disappearing, meaning I have to keep recreating them. Usually they all disappear, but sometimes just few of them. This happens on average once a week. I have searched other forums and it appears this is a widely reported problem which Apple has failed to fix for over 4 YEARS!
Does anyone have any suggestions about how to stop this happening, or whether this issue is actually on Apple's radar? I've personally reported the bug, as I know others have.
iMac, macOS Sierra (10.12.3)
