Custom RPG-Tech Modpack Build

I’ve spent countless hours testing existing packs yet never found the perfect mix of immersive RPG exploration and deep tech progression, so I’m ready to commission one. The goal is simple to state but tricky to achieve: merge Cisco’s Fantasy RPG Ultimate and All The Mods 10 exactly as-is, then layer a Stone-Age-to-Space-Age storyline on top.

Core objectives
• Combine the two modpacks 1:1, keeping every feature that makes each one special while resolving any version or dependency conflicts that currently cause crashes.
• Maintain an equal balance between fantasy gameplay and technological advancement; neither side should feel tacked on.
• Script a progression arc that starts the player with primitive tools and unlocks new eras through engaging, quest-driven milestones (no filler fetch quests).
• Deliver a fully tested, ready-to-install pack with clear instructions for both single-player and server deployment.

I’ve already hit compatibility walls, so I need someone who knows their way around mod loaders, conflict resolution, and performance tuning. Please highlight relevant experience—successful custom packs, quest design, or troubleshooting complex mod lists are all helpful proofs.

Final hand-off should include:
1. The completed, crash-free modpack (ZIP or CurseForge format).
2. A concise setup guide and a changelog of any tweaks made.
3. The quest line files and any custom scripts/data packs that power the age progression.

If you thrive on both fantasy lore and redstone-driven automation, let’s talk.
