Issues with custom difficulty icons not showing up in game

[Zobtzler]

I have added a custom difficulty (apart from settler, chieftain etc). I've added the .dds and .tex files, xlps etc.
The only thing that seems to be missing is a column in the database where each difficulty is connected to each icon.

For reference: The Players table has two columns called CivilizationIcon and LeaderIcon
These two columns have values like "ICON_CIVILIZATION_AMERICA" and "ICON_LEADER_T_ROOSEVELT".

However I can't find where "ICON_DIFFICULTY_PRINCE" gets assigned to "DIFFICULTY_PRINCE".

Does anyone know where I can find it? I've tried to look through all 3 cache sqlite database files, a bunch of XML files, but yet to no avail.

Like for many game elements there is not a direct specified "hook-up" between

<Row DifficultyType="DIFFICULTY_SETTLER" Name="LOC_DIFFICULTY_SETTLER_NAME"/>

and

<Row Name="ICON_DIFFICULTY_SETTLER"  Atlas="ICON_ATLAS_GAME_DIFFICULTY"   Index="0"/>

It is implied for nearly everything registered as a "Type" in table "Types" that its Icon will be "ICON_THING" if the Type is called "THING". The game's various User Interface lua scripts are coded under this assumption, so UNIT_BUILDER needs ICON_UNIT_BUILDER, BUILDING_TEMPLE needs ICON_BUILDING_TEMPLE and so forth.

Hmm ok.
Then it's probably something else that I've missed.
Thank you.
