I will port fix update custom minecraft mod for forge fabric neoforge mob ai geckolib


About this gig
Staring at a crash log with no idea which mod is causing it? Server sitting at 4 TPS with 3 players online? I fix broken, crashing, and laggy Minecraft modpacks so you can stop troubleshooting and start playing.
I specialize in modpack diagnosis, optimization, and setup for Forge, Fabric, and NeoForge from popular packs like ATM10, Vault Hunters, and Cobblemon to fully custom setups.
Problems I solve:
- Modpack crashes on startup or world load
- Low TPS, high MSPT, chunk lag on modded servers
- Mod conflict detection and resolution
- JVM argument tuning (Aikar flags, ZGC, G1GC)
- Forge Fabric or NeoForge conversion
- Shader setup (Iris, Oculus, Distant Horizons)
- Server setup on Pterodactyl, Aternos, Apex Hosting
What I can create:
- Custom items, tools, armor, and weapons
- Mobs and entities with advanced AI behaviors
- Dimensions, biomes, and world generation
- GUI menus, HUD overlays, and inventory systems
- Server-side SMP features and commands
- Performance-optimized code for large modpacks
- GeckoLib animations and Blockbench model integration
Message me with your Minecraft version, target loader, and mod concept.

FAQ
What information do you need to diagnose my modpack?
Please provide your Minecraft version, mod loader (Forge, Fabric, or NeoForge), modpack name, crash logs (latest.log, debug.log, or crash reports), and a description of the issue.
Can you fix startup crashes?
Yes. I can identify problematic mods, dependency issues, version mismatches, configuration errors, and other causes of startup crashes.
Can you improve server TPS and reduce lag?
Yes. I diagnose TPS drops, MSPT spikes, chunk-loading issues, memory bottlenecks, and inefficient mods to improve server performance.
Do you work with custom modpacks?
Absolutely. I work with both popular modpacks and fully custom modded setups.
Which mod loaders do you support?
I support Forge, Fabric, and NeoForge across multiple Minecraft versions.
Can you find mod conflicts?
Yes. I can identify conflicting mods, incompatible dependencies, duplicate functionality, and configuration issues causing crashes or instability.
Do you guarantee that every modpack issue can be fixed?
While most issues can be resolved or significantly improved, some problems may be caused by abandoned mods, upstream bugs, or limitations within Minecraft itself. I'll always explain the available options and recommended solutions.
Can you convert a modpack between Forge, Fabric, and NeoForge?
In many cases, yes. Compatibility depends on the mods involved, but I can assess feasibility and perform the migration where possible.
