About this Modpack

The most recent version might not be what you want. Go to versions to find what you are looking for.

Adds many mods that are similar to the ones used on the Unstable SMP (and some that just make sense to have)

Most important mods:

Unstable Generation (Only in versions 2.0+ of the modpack)

This mod adds the amplified, the great sea, the farlands (Wemmbu and Spoke versions), the mist, and the underworld. This mod is insanely well made and accurate and it deserves way more attention!

Orbital+ (Only in versions 2.0+ of the modpack)

Adds the most accurate version of the Unstable SMP's orbital strike cannons that I have seen. This also has a few more features, such as changing fishing rod mechanics so that the bobber is tied to the rod instead of the player, allowing multiple fishing rods to be used to activate different things, playing the wither spawn sound when players die, and setting a distance from deaths in which death messages will be shown.

Frequently Asked Questions

Unstable SMP Recreation server crashes or won't start – what to do?

Most common causes: insufficient RAM or wrong fabric 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.

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 €7.800000000000001/month).

Can I add custom mods to Unstable SMP Recreation without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.11). 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.

Unstable SMP Recreation server lagging – performance tips

1) Increase RAM to 8 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.
