This minor release deals more gracefully with a (reported) situation in which a multi-choice question (checkboxes) was changed to a single-choice question (select) after data was collected. NF was choking when the stories were being exported. In general it is best not to make changes to question types after stories have been collected. However, NF should now handle this particular situation more gracefully, by posting warnings to the development console (and exporting the data anyway) rather than refusing to work.
