[1.8] Drops randomly doubling and when it does, the duplicated drop is not pick-up able

[IMleader]

Hello! I am working on a mod for me and my brother like of like lucky blocks. I am starting with the basics and slowly advancing the mod. I recently ran into an issue where, when i break the block, it drops two of the drops. Not one type. My code works like this:

1. Block gets destroyed
2. Block calls DropDB.getRandomDrop
3. DropDB gets a random drop from an array of drops and returns in
4. Block loops the drops and spawns the items above it

It works but when I break it two drops come out. One which I can pick up, and the other which is strangely still registered as an entity. But I cannot pick it up. All of my code it posted on GitHub here: https://github.com/xXXIMMATTHEWXXx/BroCubes
