This faction is not compatible with Crusade, unfortunately. :(

This Faction does not use any mod's, however, with that being said does require DLC's I have updated the list of required DLC's for this faction to work.

I have unmodded game, latest ver. 1.82
Have DLCs:
Mega Events, Revenge of the Snathi, Ship Designer's Toolbox, Mercenaries Expansion Pack
Tested on my main machine and on laptop, both have same problem.
This faction is not working at all due to the following error:

The faction Zalum Efficiency has failed to validate for the following reasons and will not be available:
+Unknown Ship Style

Unsubscribing & unliking until it is fixed)

What ship style are you using? Whatever it is, it's making the faction bounce on me.
