Duplication Glitch

[RAGn]

Hello, my name is RAGnarok345, I am making this post in order to inform you that while mining yesterday I found a duplication glitch. Now, I don't know how it works, but while I was mining an accacia plank, a huge lag spike caused it to duplicate, now I am informing you about it for two reasons, one I am afraid that it might cause abusing the glicth to duplicate, second I was recently unbanned from the server after being banned for griefing, and I don't want to be banned again, so I reported this asap after I found the glitch. I hope it will be eliminated soon.

Kind regards,
