The Thunder enchantment sound effect is global. As we get more players with Thunder, the constant thunder spam is getting to be a problem.
The Fuse Shot enchantment effect is global. One player just started using it today and everyone can hear it.

Yeah I know sounds are broken, I haven’t gotten around to fixing it yet.

Sounds are getting fixed in the next update, turns out what I understood to be the volume of a sound actually gets multiplied by 16 and therefore if you have 1000 as the volume, it can be heard from 1000 chunks away...

Fixed sounds being too loud in development, will be fixed in next release
