How do you know? Connecting the exposed pad may be strongly required, and thermal vias, too. For designs that have the pad connected to ground, routing the additional ground pins to it may be reasonable (unless a separate ground connection is suggested in the component datasheet). Getting errors with this connections is mainly an issue of the PCB library definition, and possibly a general problem of your layout tool.
