Historical responses after removing a form question

For GiveCampus reporting.

The question-removal path deletes its field definition rather than erasing every contribution's saved additional-field data. Reporting also relies on stored field titles and selected columns. A missing column is therefore not proof that historical answers were deleted. Have support identify the original field key and recover the appropriate report column or scoped export. Creating a new question with a different key does not reconnect old answers automatically.
