i remember listening and marking various songs as my favorites from the master collection of 2013

but after updating the collection to 2017 it seems that a bunch of my favorites have been deleted? renamed maybe? I can't find them anywhere.

please do a cross check of your own collection versus mine, see if you can find these song-titles in there: miner; outlive no2; Intro number 101; intro number 105; intro number 42; pazasol; midi-lover; malee; tears of October; alloy run; fountain of sighs; funkey; etc, you get the point, it's a bunch of them!

thoughts? I mean they were my favorite

Only duplicates are deleted. Some files are renamed if had improper name/extension. Check CHANGELOG.txt for that changes

I did check the log before posting. There's no reference to any of these songs in the log. Zero reference. I searched one by one.

It's all there in the latest MusicPack:

Miner: FFF - Adaron Zip Portal 1.56 crk.xm
outlive no2: FFF - SAMInside 2.5.7.1 crk.xm
Intro number 101: FFF - NetLimiter Pro 2.0.9.1 crk.mod
intro number 105: VENOM - Rugrats Go Wild intro.mod
intro number 42: Dual Crew - Discovery intro.xm
midi-lover: FLG - Atomic Alarm Clock 5.85 crk.mod
malee: FFF - WebMail Spy 3.3 crk.it
tears of October: SnD - WinTools.net Pro 7.1.1 kg.xm
alloy run: FFF - SourceTec Software April 2008 kg.xm
fountain of sighs: JUNLAJUBALAM - Vegas Movie Studio Platinum Edition 9.0b b92activator.mod
funkey: PSC - A-One DVD to iPod Ripper 6.45 crk.mod

So i don't know what's your problem. The files might be renamed or moved from Others folder within a time.

PS: Personally i don't use any playlists nor music library organizers.
