The dark box that is supposed to appear behind all dialogue and loading screen tips has recently disappeared and is replaced with the pipboys "file not found" image. Dialogue still appears just not the box.
Disabling mods does not fix it but turning archive invalidation off does. I must have overwritten the file somehow but I don't know where it should be or what could have overwritten it.
I'm going to reinstall the games anyway so it's not a problem but I would be grateful if someone could tell me what the correct file is called and where it's located so I can back it up after the clean install.
