About this Modpack

Modpack Image by Avogado6

Sleepless Den has been updated to include Create 6.0 and recreated from the ground up!


Server Admins please refer to the Server Hosting section below


Welcome to the Sleepless Den.

This curated modpack focuses on Create and Ars Nouveau. Gearing is primarily done with Tinkers Construct. This modpack will be balanced around "Hard" difficulty.

There is no easy teleportation via Waystones in this modpack in order to encourage everyone to play around Ars' Portals, and Create's Trains.

Also to encourage building, somewhat easy access to certain infinite resources can be had via Create Mechanical Extruder and Create Sifting.

Also to encourage a heavier production on the Create side, Ars Nouveaus resource generation has been tuned down to cost more for Drygmy production and Portal costs.

Changes to Core Mechanics

These are some important but non exhaustive changes to core mechanics.

Movement

Combat

Death and Spawning

  • You can set a temporary spawn with Campfire Spawn and Tweaks
  • There's a whole death-centered expansion with Corail Tombstone
    • Combine the grave key with an ender pearl and you can teleport to your grave, nice and easy.
  • In multiplayer, your friends can revive you with PlayerRevive

Food and Farming

Keybinds and Configs have been changed from their defaults

  • Please explore the new KeyBind Bundles mod. It allows for a key to work for multiple binds. Here are some of the pre-configured bundles:
` - Opens up settings for several mods
. - Toggles Mute on Voicechat
LShift - Sprint (Changed for ease of use with Parcool)
LCtrl - Sneak (Changed for ease of use with Parcool)
Alt+B - Opens up Sophisticated Backpack binds
R - Quick Cast Spell 1
T - Toggle Spellbook
H - Ars Nouveau Key Bundle

While in a chest,
X - Extract all Items
Z - Insert all Items
LShift+X - Extract similar stacks you have
LShift+Z - Insert similar stacks in chest
  • You can set a favourite by right-clicking a selection. Doing so will require you to press alt+key to access the key bundle again.
  • Please feel free to change the bind and config settings to ones that suit you.

Full Modlist

Server Hosting

To avoid first time crash for the server, you will need to do additional exclusions of freecam and keymap.

Otherwise, just relaunch the server and it will fix itself.
On a new world load I recommend to the following commands:

/gamerule playersSleepingPercentage 40
/chunky spawn
/chunky radius 2500
/chunky start

This sets the player sleeping percentage to 40, as well as pre-generates a radius of 2500 blocks around spawn.

You can read more about pre-generation from Chunky docs.

Frequently Asked Questions

Sleepless Den server crashes or won't start – what to do?

Most common causes: insufficient RAM or wrong forge 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 Sleepless Den 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 Sleepless Den without conflicts?

Yes, but check compatibility: only use mods for the same loader (forge) 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.

Sleepless Den 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.
