FAQ
What information do you need before I order?
Please send me your crash log (latest.log or crash-reports folder), your mod list or modpack name, the Minecraft version, and the mod loader you're using (Forge, Fabric, NeoForge). This helps me diagnose the exact issue and confirm the right package for you before you spend anything.
Can you fix a modpack that won't launch at all (Exit Code 1)?
Yes — Exit Code 1 and startup crashes are some of the most common issues I fix. I analyze your crash log to pinpoint the broken mod or dependency, resolve the conflict, and deliver a fully working setup. Just share your logs before ordering so I can confirm the scope.
Do you support all Minecraft versions and mod loaders?
Yes. I work with Minecraft 1.12.2 through 1.21+ across Forge, Fabric, NeoForge, Paper, Spigot, and Bukkit. If you're unsure which loader you're using, just send me your modpack files and I'll identify it for you.
Can you convert my Forge modpack to Fabric (or vice versa)?
Yes, Forge to Fabric and Fabric to Forge conversions are included in my Standard and Premium packages. Note that some mods are loader-exclusive, so I'll find equivalent alternatives and test everything for full compatibility before delivery.
Can you set up a Cobblemon server with quests and menus?
Absolutely. My Premium package covers full Cobblemon server setup including mod installation, spawn configuration, quest system integration, custom menus, and performance optimization so the server runs smoothly for multiple players. Message me with your vision and I'll plan the build.
How do you deliver the finished modpack?
I deliver a complete, tested modpack file via Fiverr's delivery system — ready to drop into CurseForge, Modrinth, Prism Launcher, or your server directory. I include a short setup guide so you know exactly what to do next.
What if the modpack has issues after delivery?
Revisions are included in every package (1 for Basic, 2 for Standard, 3 for Premium). If something isn't working as expected after delivery, message me with the details and I'll resolve it within the revision window. My goal is a setup that actually works — not a one-and-done delivery.
