The quark mod adds sounds to the vanilla bundles for putting items in, taking items out, and dropping items onto the ground, and that doesn't seem to apply to betterbundles bundles for some reason, even though technically they're both just implementations of the existing yet unimplemented vanilla bundles.

I just checked and BundleItem class does have 3 Methods to play different sounds used throughout the item class

The bundles from betterbundles are missing this method entirely and don't play sound but it would be a easy fix, but I'm not sure if this repo is even remotely active anymore or not
