Sandustry Early Mistakes and Their Reversible Fixes
Early factories are supposed to be temporary, but temporary does not have to mean opaque. These mistakes matter because they spread uncertainty: one blocked or mixed route makes several machines appear wrong. Each fix below begins with a reversible observation rather than demolition.

Scaling after one successful batch
A brief burst proves only that material can pass once. It does not prove sustained supply, full-output behavior, or restart. Before widening a chamber or adding machines, run a longer interval and perform failure tests. If you already scaled, isolate all but one module and recover a small stable path. Measure that path, then reconnect capacity one branch at a time.
Sharing storage between unlike materials
A shared box looks efficient until one material settles across another outlet or returns through the wrong lane. Give raw feed, conditioned feed, valuable output, and byproduct distinct identities and destinations. If a mixed store already exists, stop all inputs, quarantine uncertain material, and rebuild clean output paths before sorting. Do not send the mixture back through an expensive process to see what happens.
Using the main reservoir as a test chamber
An experimental breach can drain the water needed for progression into a mine or factory corridor. Preserve the main source behind an isolation boundary and test with a smaller header or basin. If the reserve is already connected, close the branch before changing geometry. Create empty containment below the affected area, then lower the level through a controlled path instead of opening a wall at the deepest point.
Building without maintenance access
Compact designs often hide the lowest outlet or require removing a support wall to reach it. Leave a walkway, inspection opening, and safe excavation space around important boundaries. If a finished module is inaccessible, do not dig into it while supplied. Stop inputs, drain or clear nearby material, make a backup, and create access from the side least likely to release stored mass.
Treating every slowdown as low capacity
A full collector, covered outlet, mixed feed, or unstable water level can imitate a slow machine. Check the final destination and work backward. Compare upstream buffers: full suggests downstream restriction, empty suggests supply restriction. Only add capacity after the same stage remains constrained during a clean sustained run. Otherwise expansion adds more inventory to the same blockage.
Copying an unlabeled blueprint
A screenshot rarely shows build version, startup state, overflow, or what happens off screen. Recreate the smallest module in a test area and identify every interface. Use creator footage for observable examples, not universal numbers. If the design depends on a community workaround, label that dependency and verify save/reload plus away-from-area behavior before connecting valuable stores.
Changing several boundaries at once
Simultaneous edits destroy diagnostic evidence. Preserve the failed state, write one hypothesis, and change one inlet height, outlet width, buffer limit, or control. Run the same test again. If behavior improves, repeat to confirm before making another change. If it does not, restore the boundary and move to the next hypothesis. This feels slower but prevents cycles of rebuilding without learning.
Forgetting the recovery order
During a spill or clog, digging immediately can release more material. Use a consistent order: stop feed, isolate fluid, protect downstream capacity, preserve power if recovery controls need it, then clear the lowest obstruction. Restart at reduced input and watch the repaired point. Record the order beside the blueprint so the next failure is a rehearsed procedure instead of an emergency experiment.
