Hey Guys, my buddy and myself played this evening DayZ and both of us heard two times an misterious Sound near Krona Castle (Bogatyrka) it was like a short music (4-5 seconds) and after that i heard a louder explosion? Had someone an idea what it could be? maybe another Player with a megaphone, radio something like that or is it a bug, or something from the server etc? It was on a Vanilla Official Server and it was really Creepy. greetings
