It should work for all factions - I have fixed the "CAMPAIGN_SCRIPT.txt" myself and checked it for all factions (on "Huge" settings, but it should work for the others as well). There should be no more problems, hopefully! Currently I am playing my fist EB 1.1. campaign while using this mod (and few others and BI.exe) and so far it I have not met any troubles at all - but it still too soon to be absolutely certain. Try and see!
