Here's a link to a beta version of XGM 4.1.20 [link removed]. It should be bug free, and it should work with saved games back to version 4.1.0, but there are some complicated changes so I'm calling it a beta for now.
The changes include:
-Loyalty activated for Carthage
-Numidia converted to Carthage rebel faction
-Carthage and Numidia unit rosters merged
-Added install option to make Seleucid rebels playable as Baktria
-Added install option to reduce AI economic bonuses
-Added scripts to spawn extra stacks when cities rebel to rebel factions
