So, I downloaded forge and everything downloaded smoothly but..
It says the mod is in minecraft, Im using the "Minecraft comes Alive" for a
trial and the villagers are the same.
So, the mod is in minecraft (I.e. says 4 mods active) but it wont appear in
the game itself

Hey there
Did you right click the orb in the beginning ?
Did you ad RadixCore also to your mod folder ?

See above, sounds like a bad install.
