Sandustry Troubleshooting Helper
Pick the symptom: this local helper turns a visible factory problem into the next check, likely cause, fix path and verification step.
Result
Choose the closest symptom, then run the smallest check that can prove or disprove it.
How to use the result
Pick the closest visible symptom, then run the smallest confirming check before changing the whole factory.
What the helper can and cannot do
The result is a route to the next useful page and check order. You still need to watch the real machine, tile, or byproduct path in your save before committing to a fix.
Featured Questions
What should I do if I do not know the real cause yet?
Pick the closest visible symptom, then run the smallest check it suggests. If the result does not fit, switch pages instead of rebuilding the whole factory.
Can the troubleshooting helper fix my factory automatically?
No. It narrows the next check and the best matching guide, but you still need to inspect the actual line and apply the fix yourself.
When should I leave the helper and open a full guide?
Open the full guide as soon as one symptom consistently matches what you see, or when the helper's suggested path obviously does not fit the factory state.
