About this gig
Need a Minecraft modpack created, fixed or optimized? I work with Minecraft modpack setups for Forge, Fabric and NeoForge, including CurseForge packs, crash fixes, lag issues, mod conflicts, missing dependencies and version errors.
Whether your pack will not launch, keeps crashing, runs badly or needs to be built from scratch, I focus on finding the real cause and getting the setup stable.
What I can help with:
- Minecraft modpack creation and setup
- Modpack fix for crashes and startup errors
- Forge, Fabric and NeoForge compatibility
- Missing dependency and version mismatch fixes
- Mod conflicts and broken config files
- CurseForge and Modrinth modpack setup
- Lag, FPS and basic performance optimization
- Client and server modpack compatibility
- Existing modpack updates and cleanup
- Custom modpack testing and troubleshooting
I do not just remove random mods and hope it works. I review the pack, logs, loader, Minecraft version and dependencies so the solution matches the actual problem.
Send your Minecraft version, loader, modpack files and crash log if available.
Message me before ordering for large or custom packs, and lets get your Minecraft modpack working properly.

FAQ
What files should I send for a Minecraft modpack crash fix?
Send your modpack/profile export, latest.log, crash report if available, Minecraft version and loader version.
What if Minecraft crashes but does not create a crash report?
Send your latest.log and explain when the crash happens. Many Forge, Fabric and NeoForge errors can still be diagnosed.
Will you remove mods from my Minecraft modpack to make it work?
Only when necessary. I first look for dependency, config, loader and version fixes before removing important mods.
Can you troubleshoot a modpack that works in singleplayer but crashes on my server?
Yes. I can compare client and server mods, logs, configs and dependencies to locate server-side compatibility problems.
Can you keep my existing Minecraft world while fixing the modpack?
Usually yes. Back up the world first, and I will avoid unnecessary changes that could affect your existing save.
Can you work on private or custom Minecraft modpacks?
Yes. You can send the custom modpack files privately through Fiverr along with the issue and required Minecraft version.
Can you fix a modpack after I updated Minecraft or changed loaders?
Yes, when compatible versions exist. I can check mods, dependencies and configs affected by the Minecraft or loader update.
Do you test the Minecraft modpack before delivery?
Yes. The agreed fixes are tested for startup and the reported issue before the completed modpack is delivered.
Can I send a CurseForge or Modrinth profile instead of individual mods?
Yes. An exported CurseForge or Modrinth profile is often easier for reviewing the complete modpack setup.
What affects the price of a Minecraft modpack fix?
Price depends on pack size, number of errors, crash complexity, server involvement, optimization and custom configuration work.
