The Minecraft Bedrock Version can still copy items infinitely with bugs.

做法：首先确定区块模拟距离（例如4个区块），第二步在区块交界处放两个动力铁轨，动力铁轨一侧放一个漏斗矿车，另一侧上方放一个箱子。箱子里面放一个需要复制的道具。然后在漏斗矿车一侧连接红石中继器和红石，一直延长到4个区块以外，并放置一个拉杆，拉动拉杆激活电路，将漏斗矿车推出4个区块以外，这样漏斗矿车会被卸载。等待8秒钟，不保存游戏，点右上角的叉号直接关闭游戏程序。(之前保存游戏并退出也可触发此bug，经验证已经修复，现在点叉号强退仍可办到。）然后重进游戏，关闭拉杆，去看漏斗矿车，就会发现道具已经复制成功。一次只能复制一个道具，但是可以用潜影盒批量复制道具。这样会大大降低生存难度，破坏游戏平衡。这是一个恶性bug，希望早日修复。

Method: Firstly, determine the simulation distance of the blocks (such as 4 blocks). Secondly, place two power rails at the junction of the blocks. Place a funnel mining car on one side of the power rails and a box above the other side. Put a prop in the box that needs to be copied. Then connect the red stone relay and red stone on one side of the funnel mining car, extending it all the way beyond 4 blocks, and place a pull rod to activate the circuit. Pull the pull rod to push the funnel mining car out of 4 blocks, so that the funnel mining car will be unloaded. Wait for 8 seconds, without saving the game, click the cross in the upper right corner to directly close the game program. (The device, as shown in the figure, can also trigger this bug by saving the game and exiting it before. After verification, it has been fixed, but now clicking the cross to forcibly exit can still be done.)Then re-enter the game, close the lever, look at the funnel harvester, and you will find that the prop has been successfully copied. You can only copy one item at a time, but you can use a latent shadow box to batch copy items. This will greatly reduce the difficulty of survival and disrupt the balance of the game. This is a malignant bug and we hope to fix it soon.
