Problem Details

I was about to place a golden chest with Holding III.

Environment

• OS: Windows
• Full Forge version: 1.12.2 - 14.23.5.2838
• Mod version: v4.9.5

When I try it I get the following error, which doesn't result in a crash:

[12:59:48] [Client thread/ERROR] [minecraft/NetHandlerPlayClient]: Received invalid update packet for null tile entity at BlockPos{x=-879, y=4, z=1077} with data: {EnchantLevel:4b,Front:"north",x:-879,y:4,Luminous:0b,z:1077,id:"metalchests:tilemetalchest",ChestType:"GOLD",Trapped:0b,Inventory:{Size:81,Items:[{Slot:0,id:"minecraft:stone",Count:64b,Damage:0s}]}}

I don't know, why it has crashed though. After joining the world again, the chest was actually placed.

Lol. But regardless it shouldn't happen again after the fix is live.
