Bailiff not prospecting

Think I found a bug?

Bailiff wasn't prospecting, tried changing the bailiff. Didn't work. But noticed the bailiff would just stand next to a bench I added to the bailiff office for splendor. They would just stand there and then get food etc then go back.

So deleted the bench and the bailiff started protecting again!

Not sure if splendor items that are "used" by the population bug the bailiff out?
