I just figured out that this mod allows for multiple players to join with the job of captain. Why is this a feature? Normally when I do a campaign I only want ONE player to be in charge of the ship. I understand there are people who like to play loose with role balancing and that's all cool, but there's already a mod for that.

Also just to make sure I'm not crazy, I have indeed checked the files for the mod and in ita_jobs.xml the "minnumber" and "maxnumber" values are in fact missing from the job override bracket for captains.
