Frequently asked

Does Cobblemon: Run & Bun(Advanced Trainer AI) work on Minecraft 1.21.1?

Yes. 1.21.1 is the newest Minecraft version Cobblemon: Run & Bun(Advanced Trainer AI) declares support for, and the claim comes from the author's own release metadata rather than from a compatibility list somebody maintains by hand.

Do I need to install Cobblemon: Run & Bun(Advanced Trainer AI) on the client or the server?

Both. Every player needs it installed and so does the server, so anyone joining without it will be refused.

Which platform or loader does Cobblemon: Run & Bun(Advanced Trainer AI) support?

Fabric, NeoForge. A build for one platform or loader will not necessarily load on another, so this is the first thing to check before the Minecraft version.

Which Java version do I need for Cobblemon: Run & Bun(Advanced Trainer AI)?

Among the supported Minecraft releases above, the highest recorded requirement is Java 21 or newer. Use the requirement for the exact Minecraft version you run; previews and snapshots may differ.

What licence is Cobblemon: Run & Bun(Advanced Trainer AI) under?

AGPL-3.0-or-later, as stated by the author on the platform we synced it from. Check the project's own page before redistributing or bundling it.

How do I install Cobblemon: Run & Bun(Advanced Trainer AI)?

Install the matching loader first, then put the downloaded file in your mods folder and start the game. The loader, the mod and Minecraft all have to be on the same version, which is the usual reason a mod does not appear in game.

Where do I download Cobblemon: Run & Bun(Advanced Trainer AI) safely?

Start with the author's page on Modrinth, which is where the data here is synced from. MCReference does not host or repackage files. When available, recorded download links go to the source for that release; verify the publisher, filename and any available checksum before running it.
