Your Expectation
USB Stick should not crash my game
The Reality
check this code it calls toString() which doesn't include material namespace, which caused the deserialization to null , which crashes the game when you hover your mouse onto it in your inventory
(This one is screenshoted in JEI so it won't crash)
