ID3 Tag getting corrupted / Tag4All deletes ALL tags

[timokaaa]

Whenever I tag a bunch of tracks in Quick Tag, a few random ones end up having disfunctional tags: when I view them via Traktor they don't have any tags. When I load them into a deck it gives me the warning: "ID3-Tags could not be read for..." When I load them into TagScanner I can see the tags I created with OneTagger. However as soon as I "save" the tag within TagScanner, ALL tags disappear. (I usually use TagScanner to clean up the tags after using OneTagger, as often there are double spaces or no spaces or [;] instead of [,] etc.)

I cannot see a rule as to which tracks are affected by this. But it happens repeatedly with the same tracks, even if they have the exact same source as others that are unaffected.

Anyone else has similar issues?
