Sorry, no one has come back to you on this Arcole. I must admit I hadn’t noticed this. It is interesting.
In the Spanish, Carthaginian and Celtiberian lists the Caetrati Light Infantry have a save of 0 (i.e. no save). In the Roman list the allied Caetrati have a save of 6+ but are also more expensive. (The Lusitanian Light Infantry also get a save of 6+.)
I suspect Rick must have decided that they had some brittleness that mean they didn’t warrant a save (unless they were with the Romans). I can’t see a problem with you deciding to pay the extra point (13 points for a small unit) and giving them the save. Rick is (quite) unlikely to come around and complain if you do 😉 .
