CF2018 QoQ issue after update

Hi,

We updated our CF servers over the weekend and since the update we've had errors coming in from an area with a Query of Queries is used. Basically there is an order by in the QoQ and this is the field not being returned. It should be returned and it was until we did the updates and for now I had to manually add the field back into the select statement. It should be returned via a select query.* from original but not working now. The only one missing though is the one used in the order by clause. Anyone had similiar issues?

Thanks
