How I Found my Own Duplication Glitch on 2b2t

Summary

SalC1 recounts discovering a redstone duplication glitch while operating his own anarchy server. A player’s fast-pulsing redstone machine caused severe lag, so SalC1 and his admin team installed a plugin to disable rapid redstone clocks. While testing the replacement plugin, he noticed that it dropped more redstone than had been placed. Repeating the process could therefore generate extra redstone.

Suspecting that 2b2t used the same plugin, SalC1 tested the glitch there. The redstone items appeared to vanish because 2b2t’s anti-item-lag plugin combined them into stacks. But after collecting them, he confirmed the duplication worked: after three runs, he had 134 more redstone than he started with.

SalC1 notes that 2b2t’s redstone protections have changed over time, but the glitch was still functioning during his test. He ends by treating the video as a bug report for the plugin’s developer.

Key Points

• The discovery began while troubleshooting lag caused by a fast-pulsing redstone machine.
• The plugin, intended to prevent redstone-clock exploits, inadvertently duplicated redstone when it dropped the machine’s dust.
• SalC1 tested the same behavior on 2b2t and verified that the glitch still worked.
• He kept the plugin on his own server because redstone duplication seemed preferable to players creating lag machines.
