[1.10.2] TESR won't render item inside on world load

[RealTheUnderTaker11]

The three classes directly relating to the block

ModelBlockBase

I have a pedestal I am using to render whatever item is stored inside of it, and it works fine when I right click the block and put the item in. But as soon as I exit the world and come back, it won't render until I pull the item out and put it back in again. I traced it to the fact that the TESR thinks the ItemStack is null until I pull it out and put it back in manually. (The isItemStackEmpty() is just my own method that does a null check to make updating to 1.11 easier.) I have tried getting the capability from the tile entity which didn't help.Then I tried using the onLoad() method to remove and put back in the ItemStack inside, but that only crashed the game. Lastly I tried using the update() method to do the same thing as the onLoad(), and that did nothing at all.

What can I change to make it so they TESR/client doesn't think the pedestal is empty every time the world loads?
