Quick question. Since the update, I'm constantly hearing the sound effect for Shockwave (spellShockwave.ogg) as background noise every now and then. I have no idea what's causing it, as the timing is random the distance of the effect seems to be too, but it's driving me crazy - it sounds like my world is constantly being bombed. Is this happening to anyone else? Playing with Ars installed with Forge 518 and DW20's FTB pack, along with some of the Universal Electricity mods.
You have mages.
Somewhere that is and the sound plays when they are fighting some mobs, I suspect. Since sound in MC travels quite well they could be in a cave up to a 16 block radius from you. You are only hearing it since the update as many of the sounds were broken in the previous version.
