Editing a Speficic mobs AI, pserver

so i edited some mobs in heiharp so the would vac, and it worked, but the mobs still attacked me so i had to go in and edit the AIKey, but i couldnt find the specficific mob i wanted to edit, so i changed all the 3's (ranged AI key i think) to 6's, and every other number to 9, and now mobs dont do anything, any sugestions?

Exactly same what happened to me mrleakehe, what you need is a Data.pak Unpacker. You can find this on these forums but for some reason, it doesn't work for me. Goodluck!
