Its keep happening when I'm arresting Nua purple girl
And it didn't happen before? That same song plays at the beginning of the game, so I'm not sure why it would happen here and not earlier.
What version are you playing?
I'm playing joi play with mac version, because the windows version doesn't work on joi play (Sorry for the late reply)
How to play with joiplay?
Sorry, I don't have the ability to offer much in the way of advice for trying to play on mobile with Joiplay.
