A bug was reported where if within the the Trade interface of a TOTECS project a user tried to update the details of an address they created within the My Details page, or on the Order Details page, if the user clicked on the save button, an error would display "You must give a address 4 for this address." and the user would not be able to save the address. This issue would only occur if either the 4th address field, or the organisation address field were not turned on for the TOTECS project.
