Good idea that.
However, shops CAN be made 100% secure IF the runes that protect the shops can be set NOT for sale... at the moment you have to set the price of them to 30000 or 60000 so that people can not break in. Can this be changed?
If (unlikely) the thief has that kind of cash, he will just have to buy the rune, get in and collect all the gold that he spent on the rune and help himslef to the stock too.
However, this is unlikely.
