You need to set the multipliers as permanent in the mod settings, then restart game. There’s an option there. And never click “the button” after restarting. And Voila!!! It works !
I’m sure u are using an emulator in PC?
Okay I got it, the new "MOD Button" settings has a bug, where the key mapping stops working if you click the "MOD Button" in-game. For this I set my preferred multipliers then saved it in the setting for future.
