8. If your research is disabled (and not temporarily by the Illian world spell) then you probably have a hidden game option set. This happens because the "saved game options" are shared between mods. So if you enable game option 34 in Fall Further then when you load FfH game option 34 will be enabled (which could be a scenario option that disables research). To fix this load Fall Further and uncheck all the game options.
wheres the download??
It would be nice if Tigers had double movement in forests and Gorillas were a bit stronger.
