[share]increase your multisell secutiry

WhiteFace · June 30, 2009

Hello all,Here little addition to the multisell security. Each multisell template now have automatically generated during bypass parsing list of valid NPC IDs. Later in MultisellChoose packet current target checked and NPC ID searched in list. Also checking interaction distance. NPC list cleared on //reload multisell, so if you change html and remove multisell somewhere - do //reload multisell after //reload html.

No more "mammons everywhere and everytime", no more "by anything you want everywhere from GM Shop" (if exist on server).
