Glitching - Thieving the Fight Arena Guards

As you can see in the above picture, there's no option that allows you to pickpocket the guards located near the Fight Arena. However, with the use of a bot, players can somehow allow the game to steal from the normally "unthievable" guards for 30 GP. Interestingly, they could also be attacked, but only by talking to them; using a bot to attack them would bring the "you can't attack that" message.

Btw, I paid 1M GP for someone to test this out, since noone would do so at a lower price. :P
