@pirl8:

1/ It's not new, the framework has been known to just decide to re-parse everything on a whim, since at least as far back as FW 2.5

.

2/ Apparently, the KF/KT 5.1.0 doesn't like when the asin specified in EXTH header 113 isn't 'legit', and that seems to break KT thumbnails, or worse on the KF. (Check some calibre/kf threads for Kovid's findings on this). And calibre has been putting the uuid in there for quite some time (to support whispernet syncing, among other things), and that definitely doesn't look like an Amazon ASIN

.

(Take that with a grain of salt, because I've had broken thumbnails with untouched azw/azw3 files fresh from Amazon's 'Transfer To Computer', too

. [EDIT: But that might be because I've *sent* them via calibre, and AFAIR, it updates metadata on send even on DRM'ed books]).
