It talks about how you find your own PAFTs. Bug Abuse is not like cheating which always works, if your unable to understand simple things such as this you shouldn't bug abuse no offense.
First, player a (party leader) would make a party, then invite a friend. Player b would accept the invite. Player A would then go into the dungeon, while player b stalls/does kinship teleport over and over. While player b is stalling player a goes in and then exits the pa thereby deleting it. When player b stops stalling it would try to put them into the same coordinates as the dungeon but since it didn't exist it gave them invalid teleport and sent them to their original coordinates. If you have any more questions PM me or post below.
