I'm playing on standard XB1, doing the weekly challenge, and the in game sound stops and a crackle is heard from the speakers. I then somehow slug it to the end of the stage, quit to the menus, the sound returns, I start the next stage, having lost tens of positions on the challenge leaderboard due to the incident. And at the second sector of the stage, THE SOUND STOPS AGAIN!!!! If you are featuring completely randomized sound cutting out in your game, at least have the mercy to include a restart stage button, this is just torture. For a 90€ game to have this kind of critical bug still not fixed in 2 months is just unforgivable.
