I'm not sure if this a bug or not, but I have a Bloodrager (Blood Conduit archetype) who has Shield Proficiency, +2 Mitral Chain Shirt, +1 Ring of Protection (and other stuff that shouldn't conflict), and added a Ring of Force Shield. I equipped the ring but it doesn't show up in my AC. Why? I do have another character who has the same ring and it works fine in Hero Lab.
