FAQs

Can I get this for a snapshot version?

YES! I don't normally release snapshot versions online, but if you'd like to get this datapack/mod made for a specific snapshot or maintained for snapshot versions, please join the discord and let me know!

Why is JEI an optional dependency for the fabric mod loader version, and can I use another Items Interface?

By default modded recipies are not added into the recipie book, and are therefore not displayed. JEI allows these recipies to be viewed in an visual user interface. You can replace JEI with whatever your preferred recipie viewing interface is.

Most common cause: wrong datapack version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.1.2). You can switch loaders with one click in the panel.

Heavy Core Duplication officially supports datapack, fabric, forge, neoforge, quilt for Minecraft 26.1.2, 26.1.1, 26.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Heavy Core Duplication – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Heavy Core Duplication consumes the most tick time.
