Oh dear! Another exploit discovered! 😲 (I don't think anyone noticed this exploit, but it's hard to reproduce))

I tried to clear my inventory using the command /clear. It cleared everything except for 1 lever. I had one lever in my inventory when I did that, but it said that there were no items in my inventory, even though there is. Also, my right hand and the lever could not be seen (unless I switch to a different inventory slot). Please fix this exploit. Thank you! 🙂
