You know the basic controls but keep losing the thread
Work through the guides in order, favoring stable checkpoints over a theoretical unlock order.
Direct answer: move from basic material handling to Wet Sand, then first Gold, then a readable Gold factory, then Water and logistics fixes. Do not scale a line until you can see its input, output and byproduct path.
Work through the guides in order, favoring stable checkpoints over a theoretical unlock order.
Start with Sand, Water, Wet Sand and Shakers. The goal is not speed; it is seeing why each material moves where it does.
Keep the first Gold line small enough that you can inspect the Wet Sand input, the Shaker area, the Gold drop zone and the Residue exit separately.
Use the Gold blueprint as a concept for readable flow, not as an exact terrain-independent recipe.
If output slows down, diagnose the visible symptom before expanding. Most early failures come from blocked inputs, trapped outputs, Water loss or mixed byproducts.
Add capacity after each path remains readable under load. A larger unclear factory is harder to repair than a smaller stable one.
When you can explain how Wet Sand becomes the input for Gold production.
When the same line can run long enough for you to observe its real bottleneck.
When a visible symptom repeats after small layout changes.
When the problem is fixed without hiding the material path that caused it.
