for the first part mia vanish before the dialogue. on the 4.1 she doesn't so i tought it was a bug
For the second I will test it
please do the following:
- With the File Explorer on the folder with the game files, on the top where the path is, type: cmd
- This should open the windows terminal on the folder.
Then inside it type: .\ModificationApp.exe
This should launch the game attached to the console.
Then, load a save you might have and reset.
If it crashes, please copy the error message and tell me what it is.
