Achivement "Cultural Assimilation" BROKEN

I played through an entire game, having only gathered faith through monks on viking runestones, as the achivement required, but when i won a wisdom victory, the achivement still did not pop up, nor was it granted after in the expeditions tab.

I've tried reloading the game, but it still does not work

The game was a custom singleplayer game with 1 ally

I ran the game with DirectX

My operating system is:
Windows 10 Home
Version: 22H2
Build: 19045.4894

See attached image for validation

I would be happy to provide a save file if needed, but I did'nt see a way to tdo that when making this suggetstion / bugreport
