To be brutally honest the entire portal system needs to be reviewed and changed its far to hard to difficult to port from a to b as if its not a major town it may require a triple port. what needs to be done is to add a least one "hub" point to some of the portals i tried to make a map of each portal and its destination point and lets just say it is so overly complex its a nightmare. porting is a time sink this is the mechanic of it but multiple portis eventually lead to port caused ctd's.
