Inside of the guild hall quest folder, the player.pl is where your problem lies. This is where the answer for the pop up occurs.
Code:
sub EVENT_POPUPRESPONSE {
if ($popupid == 666) { #hateplaneb
quest::movepc(186,-393,656,3);
}
if ($popupid == 674) { #airplane
quest::movepc(71,539,1384,-664);
}
if ($popupid == 15891) { #dragonscale
#quest::movepc(442,-1954,3916,19);
}

}
if ($popupid == 416) { #kattacastrum
#quest::movepc(416,-2,-425,-19);
}
if ($popupid == 20543) { #potimea
quest::movepc(219,0,110,8);
}
if ($popupid == 21986) { #brellsrest
#quest::movepc(480,-23,-619,36);
}
}
The # before some of those quest::movepc means that line is commented out so perl wont execute those particular lines. This is why the porter wont send you to those zones.
