Frequently asked

Does Cobblemon RLM work on Minecraft 1.21.1?

Yes. 1.21.1 is the newest Minecraft version Cobblemon RLM 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 RLM on the client or the server?

The server only. Players join with an ordinary Minecraft client and install nothing.

What does Cobblemon RLM need to run?

It declares Fabric API and Cobblemon as required, so those have to be installed alongside it or it will not load. Each one is linked in the dependencies section above.

What licence is Cobblemon RLM under?

MIT, 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 RLM?

Data packs install per world: put the downloaded file in that world's datapacks folder and run /reload, or add it when creating the world. No loader is involved. On a server, the world folder lives next to the server jar.

Where do I download Cobblemon RLM 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.
