Do goofballs use only michief interactions in your game? Mine do all the time since latest patch. They don't use any other interaction, not even funny ones.
Hmm... I think they should make a jokester or prankster trait to be the one who does all the mischievous actions. Or just rename the current one. When I think of goofball I think of someone who is a little silly and is always trying to make people smile by telling jokes or making funny faces, not someone who constantly pranks people.
