When I try to cook Iron equipment in a furnace and blast Furnace it doesn't start to cook. Then I've tried in another location in my world and it works until I remove the first 64 iron nuggets, then it stops working. This is a bug because a can cook normally golden swords and it happened the same to another player.

I'm a beta player and my game version is 1.16.230.50 but this bug exist since like a month
