In any query created in a subject, the author was linked in it as the creator. If by any chance the user was later removed from the study, the queries created by that user lost the information about the author, and in some instances like the Certified Copy in PDF could not be generated. This behaviour has been modified, so the author data is replicated in each query and any response, at the time it is created. This means also that the information on the author from now on is contemporary to the query itself, so even if the name of the author is changed later, in the previous queries will remain the same when the query was created.
