As said in the forum, it was decided but never done to remove the nubian archers (it's before the -500 / -1 timeframe), to replace it with the cretan archers and to move instead a javelinist in the cc. The provided patch do the said modification. I renamed the old nubian archers to keep it for atlas/fun (I checked, there was only the basic actor).
Also, in last enrique art commit, a new pikemen champ was introduced, perhaps can we include it? (It fits well with the other ptolemaic champ).
