Not sure when this happened, but if something that like this happened, please specify in detail what happened. However, whenever you are in this type of situation always check your logs of your computer of Minecraft
You can do this by:
1. Pressing Windows Key + R
2. Typing in %appdata%
3. Press Enter
4. Go to Logs
5. Scroll all the way down to the bottom where it says "Latest" and click it
6. Find the area where the player has bypassed.
If you are able to do this, please screenshot this in logs or in-game and send it to either myself or another staff member and we will give them the appropriate punishment
.
Thank you!
