Hello,
This morning, I was in the aether building a roof and I had only one wooden plank in hand.
I put it but it was still in my hand, I made this 8 times (with one plank) before it disappears of my hands.
Later on, it happened again, with a crafting table, I placed 4 of them when I had only 1 in my hand.
Hope you will fix this glitch,
Thanks.
