Sound breaks during the battle between the Celestial Scion and the mutant boss

If you move the mutant boss to the arena where the Celestial Scion is already located, the boss theme music will break. This is possible if, for example, there are several players on the server and one of them teleported the boss using telelocator focus and a teleportation station in the arena. And this is without mods. And by the way, you cannot teleport bosses back to the main continent, i.e. you will only fight bosses in the arena - this applies to bosses that can be teleported to the arena. This can also be done in the regular version.
