Not required reading
I'll say in advance that there probably won't be a modpack for two versions 1.16.5 and 1.17.1 because there is a mod for Fresh animations starting from 1.18.2 I'll probably make a modpack for 1.16.5 and 1.17.1, but without Fresh animations support, definitely do not add to the MemoryLeakFix modpack minecraft will not be able to start this description will be updated

Frequently Asked Questions
Optium server crashes or won't start – what to do?
Most common causes: insufficient RAM or wrong fabric loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 6 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 Optium server really need?
Minimum 4 GB, recommended 6 GB for stable performance. per 8 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 €5.2/month).
Can I add custom mods to Optium without conflicts?
Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21). 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.
Optium server lagging – performance tips
1) Increase RAM to 6 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.
