here's an up-to-date example from my Hayasdan Campaign (EB 1.1)

That's a RTW bug and I think it is just chance that it happened to have anything to do with the client-ruler system in your instance. Move a family member to/from that town, it should reappear. If not, just wait and it will eventually gain its sight back.
