Frequently asked questions

How do I start hosting a multiplayer world?
Open your single-player world, go to the main menu, click the "Server" button, then select "Start Server". The mod will generate a six-digit invite code that you can share with friends.
What's the invite code and how do I share it?
The invite code is a six-digit number that appears when you start hosting. Send this code to your friends through Discord, chat, or any messaging app—they'll enter it in their join menu to connect to your world.
How do I join a friend's world?
Open the join menu in your game, enter the six-digit invite code your friend gave you, and select join. You'll connect to their world as long as you have the same mods installed.
Why can't my friend join my world?
The most common reason is a mod mismatch—you and your friend must have the exact same mod list. The mod checks this automatically and will prevent the join if there's a difference to avoid crashes.
