NPC AI Question

[Sauron]

The NPCs are still have static position (unless they aggro on something.) So I was wondering how far development in making then move has gone. The DB has walk and run speeds in it. I saw function that appear to send packets that updates npc info such as position. Also in the database is a heading field. Finally there is a SendTo function in the source code I believe in the zone\npc.c file. So is it just a bug that keeps moving NPCs from working. A packet or OP code that has not been figured out yet or just something that there has not been time for yet. I was just wondering. I would not say I'm great at it but I've done alot of C programming in the past and in addition to just testing trying the emulator as it gets released I would like to do anything I can to help.
