I don't remember when that started, but I, for one, am very glad that it did. The loophole of priests being able to carry unlimited gold without risk always seemed too metagame-ish.
But there's no way for priests to decrease their risk.
If they're going to have a chance of robbery, they should have a means of defense– like being able to "hire guards." Some kind of paraphernalia that isn't a unit necessarily?
