Adding Faction Groups to Hannibal at the Gates, missing image?

[Linke]

Hi, I´m trying to add a faction to Hannibal at the Gates. Becuase of how the Hatg ui works they have to have their own faction group.
I saw a mod on the workshop that also added factions to Hatg and decided to mimic it, but now whenever I press Hatg campaign the game crashes.

The reason for this I think is where you assign the icon for the faction group, I just wrote what all the other faction groups had but with Illergetes wich becomes factions_punic_illergetes.png
Now the mod I tried to mimic did not have a file called factions_punic_Whatever.png anywhere but only the punic_faction_groups_Whatever so the problem is really what the factions_punic_illergetes.png is linked to
Here is a link to the mod I mimiced http://steamcommunity.com/sharedfile.../?id=325391080

Well I messed up and assigned half the tables to Libya so thats why it crashed, but I still dont understand how I link a image to a faction group.
