FAQ
Why does my modpack crash when I launch it?
Most launch crashes come from a mod conflict, a missing dependency, or a mod built for the wrong Minecraft version or loader. Send me your crash log and I'll find the exact mod causing it and fix it.
My game is lagging or has low FPS. Can you fix it?
Yes. I remove heavy or duplicate mods, add performance mods, and tune the memory and config settings. You get a smoother modpack without losing the content you care about.
Why does my server crash or not start with mods?
This is usually a client-only mod on the server, a version mismatch, or not enough RAM. I check the server logs, fix the setup, and make sure players can join without errors.
Can you update my old mods to a new Minecraft version?
I can update the mods that have newer versions and find replacements for the ones that don't. I can also convert a pack between Forge, Fabric and NeoForge when the mods exist on both.
I can't get my friends to join my modpack server. What's wrong?
It's usually a mismatch between the server's and the players' mod lists or versions, or a port problem. I align the files and give you a simple guide so everyone can join.
I don't know which mods to use. Can you build a pack for me?
Yes. Tell me the style you want either survival, tech, magic, Cobblemon, etc. and your PC specs. I'll build a stable modpack that runs well on them and give you the files ready to play.
What if you can't fix my problem?
I'll tell you honestly after looking at your logs, before you spend more. That way you don't pay for something that can't be solved.
