Well, it did solve one problem. Now, when I add attibutes and go to duplicate an item, attributes and all, I get this:

1136 Column count doesn't match value count at row 1
in:
[insert into products_attributes values (0, '167', '12', '123', '0.0000', '+', '0', '1', '0', '+', '0', '0', '1', '', '1', '0.0000', '0.0000', '0.0000', '0.0000', '0.0000', '', '', '0.0000', '0', '0.0000', '0', '0')]
