if you download the Unhinged cards there are 2 cards with the Author Name / Name that is put on two consecutive fields, shifting all the values by one on the right (you can see the Unhinged value under the ID column, for example - see image
Urza Gatherer - Unhinged error
I think this depends on the " symbol in the Author Name / Name fields
Have a nice day!
I'll fix that with next release! Thanks a lot
