Hello everyone, first time post. I'm having trouble with a mod I'm developing for vic2. As you can see in the image attached, the game will not explain what's wrong. I have searched for this error and the solution is either reinstall the mod (i cannot ofc, i'm making it) or delete cache, which has not worked. Could anyone help, please?

Additional information: it's a total conversion mod. I have changed every map file, but checked everything is correct, every province has its definition, +rivers.bmp etc.
