@jjay this looks like a bug in the add-on

@hengiesel the add-on appears to be passing a note id to models.change() that doesn’t exist in the destination collection. Anki should handle this more gracefully, but the add-on will still need fixing

Yeah, I tried disabling all other add ons, deleting and re-downloading the special fields add on, re-downloading the v10 deck, etc. No luck.

So my best bet is to just wait until I see the special fields add on is updated?

You may be able to work around it for now by downgrading to 2.1.44, importing, and then upgrading again.
