Missing Rise and Fall Civilization Icons

[ThermobaricPunch]

Civilizations from the Rise and Fall expansion have no icons, being replaced by a question mark. I get this bug even with no mods loaded whatsoever. What's even weirder is that the icons load properly in the menu if and only if I use a preset game setup (with or without mods), but once the game loads the icons are gone again.

This is what the log says about the issue, but I never touched that xml nor anything regarding icons so I have no idea about what's going on:

[2189533.855] [Database] ERROR: UNIQUE constraint failed: IconTextureAtlases.Name, IconTextureAtlases.IconSize

The issue only affects icons from civs added in R&F, everything else (GS, DLCs) loads just fine.

It is weird...

I guess it is the Steam version.
Did you tried to re-validate all files?
(right-click on game in the library, properties, local files, verify integrity of game file)
