Hi...
I'm new in modding and i'm trying to start with fifa 23.
I'm trying to review the European Championship after i successfully added some new nations in the game.
I tried to follow the tutorials to modify the correct files, but now the game crashes at July 1st.
Is there someone that could help me understand where the issue is?

Thanks a lot

My main doubt is the connection between advancement and task files... If I manage correctly the different steps through the advancement file, do I still need to use the task for something?
