When I double-click on a server to open it (let's say Hypixel), it loads as normal. Then maybe I decide I don't want to play Hypixel, but Mc-Wars instead (this happens on any server, I'm using Hypixel and Mc-Wars as an example), I quickly press the cancel button as soon as it appears whilst loading Hypixel. I then join Mc-Wars. Now, this is when things get interesting.
When I press the cancel button instantly, I'm assuming I'm pressing it so fast that the server still loads in the background even though I pressed cancel. This means that when I play Mc-Wars, Mc-Wars starts loading, whilst Hypixel is loading at the same time. This causes aspects from both servers to be loaded, and when I finally join, I seem to be on a server, but this isn't either Mc-Wars or Hypixel. I'm playing on Hypixel-Wars (well, the servers combined into one server).
Here are some screenshots:
[media]Here, we can see that in the tab menu it says "You are playing on mc.hypixel.net", however the people in the tab are people from Mc-Wars (no VIPs or MVPs). The UHC Champions scoreboard is there (for Hypixel) aswell. The chat also seems to get spammed with "Unable to locate sign at ~ ~ ~".
[media]In this photo, we can see the same base concept. I have the Hypixel game menu, and in chat there is someone from Hypixel saying something in the UHC lobby. However, when I say something, it says it on Mc-Wars (I am a VIP on Mc-Wars).
[media]In this one, we can see that the signs are still glitching in chat, and there is chatting input from Hypixel but joining input from Mc-Wars.
Ask if you want any more screenshots, or need help activating this glitch. Thanks for reading,
Uiop
