Due to lag, the dropper will retain its inventory while simultaneously having dropped items into the hopper, causing a synchronization error that creates extra items. 3. Modded Server Exploits (1.7.10 Specific)
Version 1.7.10 contains known vulnerabilities when running multiple mods simultaneously. The ExploitForge repository lists several working exploits:
One block of sand and one cactus placed directly next to the portal frame on the Overworld side. minecraft 1710 dupe work
除了上述自动化装置，还有一些原理独特的手动复制方法：

Duplication was a massive issue in modded environments. Complex items—such as high-tier quantum armor, rare materials, or fully charged energy cells from mods like IndustrialCraft 2 or Thermal Expansion —could be copied. Because of this, server administrators in 1.7.10 had to heavily rely on server-side protection mods (like WorldGuard or LWC ) and custom plugins to patch out chunk-loading exploits and disable specific items. 2.7.10 Duping Today : The player on the donkey should then

The 1.17.1 dupe glitch was patched in Minecraft version 1.17.2. If you're playing on a server or in a multiplayer environment, make sure to check with the server administrators to see if they've patched the glitch.
If a player placed containers holding items inside a Spatial Rift and cut the power or forced a chunk update at a specific tick, the blocks inside the physical world would fail to disappear, even though they were successfully written to the digital drive.

在1.7.10版本中，TNT复制是一项非常成熟且实用的技术。其核心原理是，在TNT方块被点燃并被转换成实体的一瞬间，将其同时“保留”为方块，从而创造出新的TNT方块和实体。简单来说，就是活塞在移动方块时，TNT在特定时序下同时被点燃，系统没能正确处理这个状态，就产生了一个“分身”。
The timing must be perfect so that the minecart is destroyed by an explosion or a cactus at the exact fraction of a second it teleports.
: Involves pushing a Storage Minecart or Hopper Minecart through a Nether portal and attempting to remove items from its inventory at the exact moment it teleports.
The fundamental issue lay in "trusting the client." In many instances during 1.7.10, the server would accept inventory updates from the client without rigorous verification. If a player force-closed their game or cut their internet connection at a specific millisecond, the server would fail to save the player's inventory state properly. This desynchronization—where the client thinks one thing happened and the server thinks another—is the root cause of almost every major dupe method in this version.
To combat the Minecraft 1.7.10 dupe glitch, server administrators and players have implemented several fixes and workarounds:
