A bug I found that will cause the script not to start:
If you have a full inventory (even though you have coins in inventory) the bot wont start pick pocketing for some reason.
The last message in my chat log was the "you have been stunned message" im not sure if this has anything to do with it but all I did to get the bot to start was eat one food and then it started pick pocketing.
Also being able to choose the space where to stand to pick pocket i feel should be added into the script. To prevent getting reported by players when you're standing in a spot that will cause the npc to despawn. Scripts good right now if you baby sit it.
