Yesterday we have released a new version of MSSQL extractor in which a bug was present with caused failed jobs - data doesn`t end up lining up with the headers.

We sincerely apologize for the errors. A postmortem reports will follow with further details.
UPDATE 10:47 UTC: We'll be contacting all customers possibly affected by this error through support.
