About this Modpack

The RatPack is my personal modpack that I've been working on for a while now and decided to post it here because I find it quite fun to use and hope you do too.

The RatPack focuses on including open adventure like mods to give you things to do without urgent objectives (i.e. Aether, Better Nether, Ad Astra), optimization to help run the game as well as it can with these new features, and multiplayer optimization with the inclusion of e4mc to host worlds from your own PC and Player customization to add some fun to the adventure.

Anyway thank you and enjoy the pack

Frequently Asked Questions

The Ratpack 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.

How much RAM does a The Ratpack 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 The Ratpack without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.20.1). 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.

The Ratpack 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. With Mado Hosting, all servers run on NVMe SSDs with dedicated CPU cores – eliminating hardware as a bottleneck.
