If the only thing you have changed is killing units then it might be that your script's killing is including garrisons which in turn drops public order in some settlements leading to revolt. And when they rebel they revert to some other faction instead of the slave faction, in this case your emergent factions and thus making them appear in the process. Just a theory. I know of two cases where a rebelling settlement goes to some other faction:
1) faction_creator in descr_strat.txt, e.g. if mongols then this settlement rebelling could go to the mongols faction
2) shadow factions in descr_sm_factions.txt, e.g. if mongols is a shadow faction of the faction whose settlement rebelled
However, as far as I know neither case occurs if the faction (mongols) is not yet alive and has dead_until_resurrected in descr_strat.txt.
