About this Modpack

Constructum

a Modpack with focus on QoL features, multiplayer, and long term playthroughs. I've decided to trim down on the amount of content mods, mainly focusing on Create and Farmer's Delight with a few smaller mods like Portfolio, Clayworks, Woodworks, etc. to keep the pack lightweight, stable and performance friendly. This pack revolves around staying true to the core sandbox nature of Minecraft whilst implementing custom recipes, textures, and configurations that ensure every addition complements eachother perfectly. If you are searching for a modpack tailored towards a set progression path/questing, I'd recommend looking elsewhere.

Frequently Asked Questions

Constructum 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 Constructum 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 Constructum 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.

Constructum 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.
