New Flags may not show, because New Flags and hi-res mod partially overrides the same defs. I don’t remember proper ‘enabling’. First I enabled New Flags mod then high-res mod or… opposite.
And you are the first that reporting Small Era submods don’t work. Don’t know really why, because most of them are small and simply and they should work perfectly. I know it’s silly question, but… in order to work any submod - you must enable main Small Era Mods mod as well!
