Integrate the 1.0 Grand Portal into a scalable factory layout.

Quick answer

Build the smallest working version first, confirm that inputs stay supplied and outputs keep moving, then scale. Alchemy Factory rewards visible, modular logistics more than clever but fragile spaghetti routing.

Plan it as a hub

Large utility structures deserve dedicated floor space and clear access rather than being squeezed into a finished production row.

Keep logistics readable

Route portal-related inputs and outputs through labeled lanes or dedicated storage so they are easy to distinguish from normal production.

Test before expanding

Confirm the portal behavior in the current save and patch before reorganizing multiple floors around it.

Keep old saves in mind

Major-version systems can interact differently with factories built before 1.0. Back up saves before large restructures.

Troubleshooting checklist

1. Confirm the current patch and unlock state.
2. Inspect the upstream input before rebuilding the output side.
3. Check for full storage, blocked belts, or an empty support resource.
4. Test one module in isolation.
5. Scale only after the isolated module stays stable.
