Change hero name.

The file simply remained in the folder, and nothing changed.

That's how it should be. All key .txt files are embedded within the game, and the game retrieves them from there. However, if the required file is located in the Data folder, the game will prioritize using it from there. This principle is used in the online game with modified .rmg, .array, and .cranim files, etc.

P.S. For the modified file to work correctly, you need to restart the game.
