About this Modpack

This pack is intended to be used as a server pack for the Assembly Assembled modpack. This pack removes client side mods from the main pack, as to allow fewer compatibility and run issues. While this pack isnt, by itself, a server, it is updated to work with docker images to make that process easier to install. For all intents and purposes, this pack will maintain parity to the main pack.

Frequently Asked Questions

Assembly Assembled | Server server crashes or won't start – what to do?

Most common causes: insufficient RAM or wrong neoforge loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 8 GB. For "Mixin" or "ClassNotFoundException" errors: modpack version and loader don't match. With Mado Hosting, loader and Minecraft version are auto-configured on modpack install – preventing most startup issues.

How much RAM does a Assembly Assembled | Server server really need?

Minimum 6 GB, recommended 8 GB for stable performance. per 5 players. Important: Minecraft modpacks need more RAM than vanilla – plan extra per additional player. With Mado Hosting, you can scale RAM up live at any time without data loss (from €12/month).

Can I add custom mods to Assembly Assembled | Server without conflicts?

Yes, but check compatibility: only use mods for the same loader (neoforge) and same Minecraft version (1.21.1). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.
