UI Interfaces icons not showing

[El Santo Padre]

Hello.
Im doing some facelift for the Diadochi Total War Mod. Ive been redoing their faction icons, however now that Ive finished the designs im facing a weird bug. I have done all required steps to change the icons, but some factions still refuse to show the new icon somehow, here let me show:

Evidence 01.
Here you can see the full menu of factions. Im choosing the Independent greek faction

Evidence 02.
Here you can see that in game all icons are shown as in original DTW. I know youll say "Hey you might have forgotten to update the UI Interface" so let me move onto....

Evidence 03.
When i choose a different faction, in this case the Ptolemaic Kingdom the game does show all my new icons. Even weirder you can notice in screen 02 that even the ptolemies icon was showing as vanilla and now os updated.

Evidence 04.
So, final Evidence my strat map UI showing that i have in fact changed all icons, which raise the question "wheres is the game engine taking the old icons from if they have been effectively erased?".

You haven't updated all the required files.

Here are the references:

Menu symbols: Data\menu\symbols
Campaign UI symbols: Data\UI\<CULTURE_TYPE>\INTERFACE
Loading screen symbols: Data\loading_screen\symbols
Campaign banners (over cities in campmap): Data\banners
Battle flags: Data\models\textures
Captain banners: Data\UI\CAPTAIN BANNERS
Empty city flag: Data\models_strat\textures (must also have a proper CAS model in Data\models_strat)

I believe that's all of them.

You'll also need to update descr_banners.txt and descr_standards.txt

Just remember to update all cultures

Good luck!
