Okay so basically I was playing around in Creative mode and I thought I would add a jukebox to my build, so I decided that I would and I spam clicked the jukebox with pigstep and it bugged out. The audio was playing but no disc in it.

What I expected to happen was...:
Duplicating Music Discs

What actually happened was...:
The jukebox playing the audio while there is no input of the disc

Steps to Reproduce:
1.Craft a Jukebox and take any disc you'd like
2. Spam right click 
3. Take out the disc
