Events that trigger a full rescan of all Library [tags]?

[emmaoninternet]

Over the past couple days I've somehow managed to trigger several full library re-scans (tag/metadata only? - the whole scan takes <30 min, maybe way less) while fiddling w/ stuff in MusicBee and I'm not sure why; each time I haven't even realized one's started until it's several 1000 into the scan:


I don't believe it's occurred, thus far, as a result of adding any files to the Library/designated Inbox watch dir, but I'm regularly messing with all sorts of MB options, custom+virtual tag formulas, etc, so I'm sure it's something I've done/am doing to trigger the behavior, but process of elimination is hard when I keep missing the start of the scan :\  There's seriously all sorts of crap I've changed that could be related, but it's possibly noteworthy that I also very recently changed the 'save mp3 tags as' option from ID3v2.3 to ID3v2.4 under Preferences > Tags (1) > tag storage.

Just wondering if anyone knew of any particular events/actions that will always trigger a tag(?) re-scan or if I might be able to derive some info from a log file or what-have-you. Not a big deal, just curious about what I've done to cause this new behavior. Thanks!

Any time you edit the "custom tags" section, it will do a full re-scan.

Ah, so it does! Thanks - that was exactly what I was looking for
