About this gig
Is your Minecraft modpack crashing on launch, showing Exit Code 1, or making your modded server lag?
I fix existing Minecraft Java modpacks and servers using Forge, Fabric and NeoForge. I inspect crash reports, latest.log, mod versions and configs to find the cause and test the agreed repair.
WHAT I CAN FIX:
- Minecraft modpack crashes and Exit Code 1
- Forge, Fabric and NeoForge loader errors
- Mixin crashes, dependency and mod conflicts
- Wrong Java versions and missing libraries
- Client/server mismatches and connection errors
- Server startup failures and watchdog crashes
- TPS lag, MSPT spikes, RAM issues and low FPS
- CurseForge, Modrinth and Prism Launcher issues
- Broken mod configs, datapacks and KubeJS scripts
- Cobblemon and large modpack compatibility
- Apex, BisectHosting and server configuration
- Mod updates, duplicates and version mismatches
- Performance profiling and stability testing.
I work with backups and clear handover notes. Complex code rewrites, full modpack creation and ongoing hosting are separate services.
Send your Minecraft version, loader, latest.log or crash report, and symptoms before ordering. Never share hosting passwords.
