I was playing Minecraft on my computer. I have a decent internet. I tried to connect a server, when it was on Connecting to Server, I returned and quickly joined another server. When I was on, I Could see the chat of both servers, I could see the 2nd server that I connected, people could tp me to somewhere and it would tp me to exact same coordinates on the 2nd server as well, and I almost got banned on the minecraft server Hypixel while demonstrating this bug. I searched this bug, and there were only 1 youtube video about that. https://www.youtube.com/watch?v=eZh0vXrj1xc is the video. It's nearly the same, but he could fly on the server, and nobody could see the person. But in my bug, I could play on the 2nd server, when I type, it would send the message to both servers, the tab list becomes messy, the sun and moon becomes messy, I could see the chat on both servers. I was going to search for a forum that is only for server glitchs but I couldn't find so I posted it here. Please ignore the affects version part, it affects nearly all versions.
