Contact Reference Field Cutoff on Export
On a brand new Drupal 7 / CiviCRM 5.6.0 install I created a custom field group for Grants and added one Contact Reference field and then created 2 grants. When I search for grants and export and try to export that Contact Reference field, the name of the Contact is limited to 16 characters.
Further testing indicates that the name of a Contact Reference field on a Contact record also is limited to 16 characters when exported.
