I'm trying to make it so that I can break a block and place it back down and it keeps the TileEntity data from before. I managed to get this working... sorta. When I break a block it drops a ItemBlock of with the data stored from the tileEntity. I can place it back down and it is good, but if I break the block, and then break another of the same block with different tileEntity data, they both end up with the data of the second one broken. This always happens to all of the blocks when they exist as an item in the world, whether it be on the ground or in a chest, they always change their data to the most recently broken block.

 

Here is my code:

Okay, it's fixed now. Thanks!
