Trust me i know how thieving works, i have had my fair share of them
For instance this one fella (i wont name names or guilds) must have been abit pissed because just 10 minutes before had slapped him silly and robbed his ass, walks past me at Brit bank, emoting *steals from pack in revenge*. Another time, infact my first back in game in over a year. My poor old mage had his mandrake root stolen randomly straight out of his pack at Brit bank.
As ive said before ive no problem at all with people stealing off my characters, just use the yellow bags i carry. Also especially with Raul expect instant trouble if i catch you snooping or attempting too steal from him.
