About this Modpack

Just a Fabric modpack consisting of various optimization, QOL, and a few additional decoration mods. I originally made this for my Wife and I, but a few of my freinds also really enjoyed playing it, so I decided to post it here as well! Currently , I have over 40 hours in the pack, and havent had any crashes or issues. This pack also supports dedicated servers (Ive been running one during mod curation just to make sure everything works as intended). I recommend dedicating 6-8GB of RAM to the client and server.

Frequently Asked Questions

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 BubbleNaut Survival 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 BubbleNaut Survival 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.

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.
