Until I started reporting this bug I wasn't 100 percent sure this was even a bug, but this is a huge problem. I'm in my survival world and I'm on the surface at day time and I get hit with the scariest cave sound I've ever heard yet, scariest because its day time and that's definitely not supposed to happen, btw I wasn't underwater. then I go to my green hill super flat world and to be honest, it was night time but as soon as I spawn in another cave ambient sound plays. then as I'm typing this I have my tv on, on the same world and another cave sound plays, which freaked me out. and after I hear this I check the world and its midday, in my green hill zone map. now the only thing I've haven't confirmed is that if I was unknowing-ly meeting the requirement for the mood to increase, cause super flat words usually generate below-average diamond level or if this is constant in the survival world, but for now im muting ambience sounds.
