About this gig
Is your Minecraft modpack crashing on launch, lagging every few seconds, bringing out the error exit code 1 or refusing to load a world? I fix modded Minecraft instances fast using real crash reports and log analysis, not guesswork.
I diagnose dependency version mismatches, mod conflicts, worldgen mods misbehaving, TPS/FPS drops from heavy entity-spawning mods, texture pack and shader issues, and multiplayer connectivity failures. I read your latest.log or crash report line by line and pinpoint the exact mod causing the problem.
What I Offer:
- Crash report and log analysis to find the root cause
- Fixing mod dependency conflicts and version mismatches
- TPS/FPS optimization using Spark profiling
- Worldgen mod fixes (Terralith, Tectonic, Distant Horizons)
- Server connectivity fixes (players can't join, shows offline)
- Texture pack, resource pack, and shader fixes
- Modpack curation and compatibility testing
- Clear explanation of what broke and how to prevent it
TOOLS
- CurseForge
- Modrinth
- Forge
- NeoForge
- Fabric
- Spark Profiler
- KubeJS
- Sodium
- Geysermc
- Jarvis
Send your crash-reports folder or latest.log and I'll tell you what's wrong before you even order.

FAQ
What info do you need to start?
Your latest.log or crash-reports folder, plus your Minecraft version and mod loader (Forge/NeoForge/Fabric).
My game says "missing mods" but they're installed can you fix that?
Yes, this is almost always a version mismatch or duplicate mod ID conflict; I resolve it by tracing the exact dependency chain.
Can you fix TPS/lag on my server, not just crashes?
Yes, I run Spark profiles to find which mod or entity type is eating tick time and recommend config/removal fixes.
Do you work with NeoForge and Sinytra Connector setups?
Yes, including Forge-on-Fabric compatibility issues via Connector/Forgified Fabric API.
What if there's no crash log, just a freeze?
I can work from partial logs, a client profile via Spark, or a screen recording of the freeze to narrow it down.
Can you fix worldgen mods that aren't generating features (mountains, biomes)?
Yes, this is usually a config scale issue or a conflict with another worldgen/generation mod.
Do you fix texture pack or shader issues too?
Yes, including packs not applying, folder structure errors, and shader-related crashes.
Can you help if my friend can't join my server?
Yes, connectivity/offline-status issues are usually port forwarding, whitelist, or version mismatch related.
Can you curate a modpack from scratch for compatibility?
Yes, this is covered in the Premium package.
What modpack sizes have you handled?
I've worked with packs from 50 mods up to 570+ mods.
