So i have been running out of spaces so i move them in my sd card storage and they work but everytime i add a modded game from internal to external storage it doesn't work it just opens and closes.appvalleytutuapptweakbox
you should just keep it to your internal. But as you said you are running out of spaces.
So you would need to install your files first and put it to your sdcard.
And sometimea it can really put and get you to crashing issues since you used sdcard.
Make sure to allow all permissions of the game
