About this Modpack

Reason for Archival:

This version has been archived so I can focus on making the original UnstableCraft more optimized, rather than making a band-aid fix for a problem that should've been fixed to begin with.

About

A chaotic modpack with every mod imaginable, inspired by CrazyCraft or InsaneCraft. This is a personal modpack for some friends of mine on a server, but I might as well make some ad revenue money off of it. We wanted the server to be a loser's version of the Unstable SMP, but that didn't work out, but in remembrance of the original idea, it is called UnstableCraft. Contrary to the name, I hope to make the modpack as stable as I can.

Performance & Stability

This is a minimal version of UnstableCraft, featuring only optimizations, essential utilities, and all server-side mods. This version has a much larger emphasis on performance and stability than the original pack.

Content

This modpack will have the same content as the original modpack, aside from some client side changes.

Multiplayer

UnstableCraft Lite is compatible with the server that it is made for.

Frequently Asked Questions

UnstableCraft Lite 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 6 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 UnstableCraft Lite server really need?

Minimum 4 GB, recommended 6 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 €8/month).

Can I add custom mods to UnstableCraft Lite 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.

UnstableCraft Lite server lagging – performance tips

1) Increase RAM to 6 GB+. 2) Reduce server view-distance to 8 (server.properties). 3) Pre-generate chunks with the "Chunky" plugin. 4) Use /spark profiler to check which mods consume the most tick time. With Mado Hosting, all servers run on NVMe SSDs with dedicated CPU cores – eliminating hardware as a bottleneck.
