Forced to Use Goodreads for Import

I make a LOT of imports into LT to update Tags and Collections using one standard csv file with:
title, author, isbn, tags, rating, date read with no problem for 4000 books.
Just now I used exactly the same format for 60 books and was told you need to use goodreads import for these books.

This has now happened several times and in looking at GR import it didn't seem plausible. So, I just gave up on the import and went to do other things.
Today I really want this important and want someone to tell me why I can't do it.

The import system is being revamped by @knerd.knitter. Unfortunately, she's left for the weekend, so I don't think you'll get your answer until Monday.

>2 timspalding: Thanks Tim, just getting an answer is fine with me.

>3 JoeB1934:

So it should be happening… but only once the new system is in place!

It should not be happening for your format. It should only happen if it matches the GR format exactly. I don't know what changed that caused it to happen. I'll have to look on Monday.

I've pushed up a fix so this won't happen. I'm still not sure how it suddenly started to happen, but it should not happen any more.

>6 knerd.knitter: Thanks VERY much as I realize that revising the import system is a MAJOR task. I have full confidence that it will be beautiful and a realization of a dream for many members.

>2 timspalding: it never came to my mind that @knerd.knitter was a woman. Sorry :-(

>8 .mau.: I check out new employees' profiles as the first thing. (And the T-shirt on her profile photo still makes me smile :-)
