When I try to open the Advancement screen with the following advancements:
advancements/Test/root.json: https://pastebin.com/TtKsdxef
advancements/Test/basic.json: https://pastebin.com/eVKg5KQR
advancements/Test/advanced.json: https://pastebin.com/bMQSVw0n

When Root and Basic are Granted to the player

In the screenshot you can see that as soon as I open the "Suck those Items" tab, the game crashes.
