About this Modpack

Sleepless Nights Logo

Sleepless Nights is all about expanding the true quality of what horror is in Minecraft. We are trying to make this mod-pack as scary as possible while keeping the original Minecraft blocky feel. All this is possible through our dark nights, expansive mobs, ever-changing terrain, and story-based quests. We dare you to try if you believe you can take on this pack.

Performance

Sleepless Nights is made with optimization in mind. We know not every PC will be able to run our mod-pack considering the level of shaders we have installed. If you are having frame issues please try the following;

Reducing render distance by a few chunks

Lower simulation distance

Increase the RAM maximum for the mod-pack

Under no circumstances should you turn the shaders off.

Frequently Asked Questions

Sleepless Nights 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 Nights 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 Nights without conflicts?

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

Sleepless Nights 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.
