Open the game first, for example, if you want to modify your mp player, click Edit Character, then switch back to the desktop, open the modifier, click the mp Character bar, read it first, and then modify it. Don't forget to save after the modification, and then switch back to the game and save again when you exit edit mode.

Similarly, editing other dynasties or ordinary ones did the same.

The automatic saving function of the modifier can also be adjusted to manual saving.
