Function $this->db->insert_id() to get last inserted record id always returns 1

For reasons unbeknownst to me, it is now working. The only change i made was switching from this

Code:

return $this->db->insert_id();

To this...

Code:

return mysql_insert_id();

Not strange in itself. But when I switched back again the first option worked too!

No idea what's going on there, but it's working now.
