About this Modpack

Stasis - the town of four ages!
A collaboration between 76 modders, as hosted by ModFest.

ModFest 1.21 was a mod development jam that ran from October 11th through November 4th, 2024.

This modpack contains all submissions, as well as a showcase world built by participants to show off their mods!

Key Features:

Witness the dawn of 58 mods, including Armistice, Charta, FBombs, and Life-Size Bdubs!
Explore a circular world split into four "ages" - Stone, Iron, Industrial, and information!
Traverse the map with prehistoric angry birds, fancy bombs, ninja outfits, and a lot of watches!
Whistle along to over an hour of original music made just for the event!
Find and earn 130 collectible "shards", tracking booth visits, exploration, and mastery!
Decide for yourself - was the town of Stasis really eaten by a world-swallowing dragon? or is that just what the locals believe?

Heading down, fragment? Brace for impact...

ModFest is made possible by the modding community.

A full list of credits for each submitted mod can be found on the submissions page.

This modpack and world was originally showcased on a multiplayer server in the fall of 2024.

Frequently Asked Questions

ModFest 1.21 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 ModFest 1.21 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 ModFest 1.21 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.

ModFest 1.21 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.
