Hello! Well this is a really cool glitch. Usually people get really mad at you but trust me its hilarious!!!!!!!!!! Also people can't get out of your barn unless if they log off or use the map.
1. Go to a server with a ton of people.Also make sure your how is open for everyone 2. Say stuff that will convince people to go to your barn like making pet tryouts or something. 3. Say that a couple times so more people will come (Don't say it to much times or people will get bored in your house and leave). 4. When you go to your house lock it.
Then go to your barn and tell them its been canceled or its in your house. Then listen them scream!!!! Have fun!
