I love Nintendo as well!
You turned on your wishlist comments field?
Actually, not a false alarm. So I turned on the comments field and only my most recent (like 7 or 8) items had comments. All of my older games comments on the list were still gone.
I have since gone through and rewritten most of them. But I just thought I would let you know in case other people may be having the same problem and not realize it.
