Placing an amethyst bud or an amethyst cluster plays the placement sound twice

The bug

When placing an amethyst bud or an amethyst cluster, there are two sounds played (actually just one, but two dings). This is inconsistent with all other amethyst sounds, which only have one single tone.

How to reproduce

1. Obtain an amethyst bud (any size) or an amethyst cluster and place it down
2. Listen, and notice how the placement sound is played twice
