Expected:
Right clicking on a furnace doesn't crash the server.
Observed:
Right clicking a furnace crashes the server.
Reproduction steps:
I wish I knew, been trying all afternoon.
I have a saved version of the world that crashes every time. Can provide a link privately.
If I break this specific furnace and replace it, the new furnace doesn't crash the server. I parsed the .mca associated with the block and it seems the furnace doesn't actually exist within the chunk's tile entities.
Block in question is:
/setblock 215 12 -368 minecraft:furnace[facing=east,lit=false]{CookTime:0s,BurnTime:0s,Items:[],RecipesUsedSize:0s,CookTimeTotal:0s,Lock:""}
Can you upload the world or the chunk where this is happening?
