- Package, test and update CurseForge or Modrinth modpacks
Need a crash fix, mod compatibility repair, server setup or custom modpack configuration? I review your files, confirm the scope and test agreed fixes. You receive updated files and a clear handover.
Send your Minecraft version, loader, launcher and latest crash log before ordering.
