À propos de ce service
Is your Minecraft modpack crashing on launch, lagging, or throwing Exit Code 1? I fix Minecraft modpack crashes, mod conflicts and server errors by reading your crash report, then testing the fix.
WHAT I OFFER
- Crash report and latest.log diagnosis
- Mod conflict fix: missing dependencies, duplicate mods, wrong loader versions
- Modpack optimization: FPS, RAM and JVM settings
- Custom modpack changes: add, remove or swap mods and edit configs
- Datapack errors that stop a world or server from loading
- Server optimization and lag fix for Forge, Fabric, NeoForge and Cobblemon
HOW IT WORKS
1. Send your Minecraft version, mod loader and crash report.
2. I find the cause and tell you the plan before I start.
3. I fix it and test that the pack launches.
4. You get the working files and a short note on what changed.
NOT INCLUDED
Writing new mods or plugins from scratch, or fixing mods their author has abandoned. If the cause is outside my scope, I will say so before you spend more.
Message me before ordering with your crash log, and I will tell you honestly whether I can fix your Minecraft modpack.

As a professional Minecraft developer, I specialize in resolving complex modpack crashes, performance bottlenecks, and server instability across Forge, Fabric, and NeoForge ecosystems. Utilizing deep crash log analysis and Spark profiling, I efficiently diagnose stack trace errors, resolve broken mod dependencies, and eliminate tick lag to optimize server TPS and client FPS. From precise modpack loader conversions to critical hotfixes and server-side performance tuning, I deliver stable, high-performance environments. Share your error logs or technical requirements to begin.

FAQ
Which Minecraft versions and mod loaders do you work with?
Java Edition packs on Forge, Fabric, NeoForge and Cobblemon. Send your game version and loader before ordering and I will confirm I can take it. Bedrock is not covered.
What do you need from me to start?
Your Minecraft version, mod loader, mod list or pack link, and the crash report or latest.log from the crash. No passwords: if I need server access we will use a safe temporary method.
Can you fix any crash?
Most crashes come from mod conflicts, missing dependencies, wrong versions or bad settings, and I can fix those. I cannot fix a bug inside a mod's own code or a mod its author abandoned.
Will you make my modpack faster?
I tune settings, mod choices, RAM and JVM arguments to improve performance. I do not promise a fixed FPS number because it depends on your PC and the mods you want to keep.
Do you fix server lag and server errors?
Yes for Forge, Fabric, NeoForge and Cobblemon servers: startup errors, mod conflicts and lag causes. Send the server log and mod list. Hosting problems on your provider's side are outside my control.
Can you fix datapack errors?
Yes, I can find why a datapack fails to load or breaks a world, such as wrong format or version. I do not write large new datapacks from scratch in the Basic package.
What if you cannot fix my problem?
I will tell you before you spend more and explain what I found. Message me first with your crash log so we can agree on the right package.
How many revisions and how fast?
Basic: 2 days, 1 revision. Standard: 4 days, 2 revisions. Premium: 7 days, 3 revisions. If the pack crashes again for the same cause I fix it within the revisions.
