If a theme is selected for a system and Real Stars are switched on, the theme will not be respected for adjacent systems - ie, the real name will be used, instead of the one generated according to theme, regardless of there being a theme set. I think this might be unintentional; after all, if you want the generic Wolf 235, Gliese 753, etc names, you would have switched the theme off. If themes were respected on Real Stars games, you could have real stars with automatic themed names, rather than the defaults.
