No... What hlapex did my little stupid fellow was to send a buy packet from the Gm shop the GMs Buy things... (its in their console) From there they buy items for 0 adenas... What the patch does is what exactly Maxtor said... It blacklisted the packets that are send to Npc traders.. I am sure about it because once (i was gm) and i targeted an npc trader and tried to buy from the admin shop.. Then i got the well known message... Illegal action, Gm informed bla bla bla....
Try to sniff a buy packet when u buy something... Then send it again... You will buy the item normaly but you will lose adenas as if you had bought it normaly... NO kick... No hlapexs moves detected...
