Data column disappeared from the database

Dear Community, I have just found out that the entire column of the data (field with a calculation based on the inputs from other fields) was deleted completely without our intervention. The missing data can be retreived neither from downloaded file not from the data view in the Kobo interface.
The missing field is filled automatically based on compulsory data fields above in the form and those fields are still present in the database.

Do you have any idea what could have happened and how it could be prevented?

Did you check your form with the Online validator please?
Did you change the form after the previous period?

@janrikovsky, could you let us know which column existed previously but is not missing? Could you also let us know if you made any changes to your form and redeployed the project?
