Describe the bug
Crashes while using item

Additional context
tea_kettle-1.16.4-0.3.2.0

In a single player, put down a teacup and some rose petals then right-click on the boiled tea kettle

it is normal in multiplayer players, I kind of don't understand, but I looked at the code this is really a possible bug

ono, a crash
could you give a bit more context on the crash? I really don't know how to reproduce it.
what item were you using? was there anything in the cup?

well this is weird, IDEA says an item stack can never be null, so that line shouldn't be causing any trouble. still, I'll try reproducing it with the steps you gave me, and see if I can fix it. thanks!
