Songs of Syx: why is my colony collapsing?

“Trying not to quit the game in frustration. Help needed.” Seventy-five replies, and the thing they have in common is that each responder diagnosed a different problem from the same description. They were probably all right. A colony that is falling over is usually not failing at one thing — it is running three balances slightly negative at once, and each one masks the others.

That is why a single answer never lands, and why a checklist beats a guide here. The point is not to learn what is wrong in general. It is to establish, in order, which of five balances is actually negative in your save.

Why symptoms lie in a colony sim

Every failure in this game propagates sideways before it becomes visible, and it becomes visible somewhere other than where it started. Three examples that account for most misdiagnoses:

• Idle workshops look like a labour shortage and are usually a hauling shortfall — logistics workers, not workshop staff, are what actually moves goods between buildings, and the workers are there while the inputs are somewhere else.
• Falling happiness looks like a services problem and is often a food variety problem — food access already grants fulfilment on its own, and species get an additional fulfilment and health bonus for eating foods they prefer, so a colony fed on the wrong staple can be well-fed and unhappy at the same time, which no amount of building fixes.
• A stalled economy looks like a trade problem and is often an industry quietly consuming more labour than it returns.

In each case, treating the symptom makes the underlying balance worse, because the treatment consumes exactly the resource that was short. That is the mechanism behind the death spiral people describe: the harder you respond, the faster it goes.

Work down it and keep your place

Colony audit: find which balance broke

0 of 24 checked Reset

Food

Days-of-food falls even though the fields look busy

• Read the actual per-day consumption off the food panel rather than assuming it scales with buildings
• Count cultivated tiles, not placed fields — unstaffed tiles produce nothing and still show as farm
• Check fertility on each field; a low-fertility field costs the same labour as a good one
• Confirm harvests land in a season your storage can actually absorb
• Count how many distinct food types you produce against how many your population mix asks for
• Verify slaves and animals are included in your demand figure, not just citizens

Needs and happiness

Happiness sags at a population you handled fine before

• Find the lowest-covered need, not the average — the floor is what sets the ceiling
• Check service buildings are staffed, not merely built
• Check the range of each service against where people actually live
• Look for a category that is at zero rather than merely low; those behave differently
• Compare needs per race before assuming one plan covers a mixed population

Logistics

Workshops idle while the warehouse is full

• Time one hauler walking your longest route and convert it into trips per day
• Compare units produced per day against units your haulers can physically move
• Check whether a round trip is mostly walking or mostly loading — they call for opposite fixes
• Confirm a nearer stockpile exists for high-volume, low-value goods
• Check that hauler jobs are not competing with a higher-priority job for the same people

Labour and slavery

Population grows but nothing gets built any faster

• Count how many workers are tied up guarding, hauling or administering rather than producing
• Work out net worker-equivalents from slaves after guards, food and replacement losses
• Check the share of population held as slaves against your own risk line
• Confirm employment is capped by jobs, not by unmet needs keeping people off work

Trade and money

Income looks healthy and the treasury still drains

• Price one imported good in worker-days and compare it with producing it yourself
• Check how many shipments must be in flight to keep a good permanently in stock
• Separate one-off sales from recurring income before planning around the number
• Confirm no industry is running purely to feed an export that no longer clears

The order is not arbitrary. Food comes first because a starving population fails to work, which corrupts every labour and throughput figure you would collect afterwards — you cannot measure a hauler’s trips per day while the hauler is malnourished. Needs come second for the same reason one step removed. Trade comes last because it is the only one of the five you can suspend immediately without consequence, so it is never the emergency.

Where each group hands off to a calculation

Several items on the list ask you for a number rather than a yes or no. Those are the ones where the answer genuinely depends on your city and cannot be looked up:

• The food group’s arithmetic is in why your days of food never go up, including the row that separates a variety shortage from a volume shortage.
• The needs group resolves to a single binding category in one need is capping the rest.
• The logistics group turns into a required hauler count in how many does a route need.
• The labour group’s slavery overheads are netted out in does it actually pay for itself.
• The trade group’s coin-to-worker conversion is in import it, or make it yourself.

Progress on the checklist is stored in your own browser and nowhere else, which matters mostly because this is a multi-session job. You will not get through all five groups in one sitting, and coming back to a half-finished audit is much better than starting the diagnosis over.

After you find the negative balance

Fix one thing, then run the list again from the top. This feels wasteful and is not: the constraint moves. A colony that was short of food and short of hauling is, after the food fix, a colony with more population and worse hauling, because the balance you corrected fed the one you did not. The second pass is usually much faster than the first, and it is the pass that catches the problem you would otherwise have introduced.

The one thing not worth doing is acting on all five at once. Every correction costs labour, all five draw from the same pool, and a colony already in trouble cannot fund them simultaneously — which is the mistake at the bottom of most of those frustrated threads.

Keeping this current

Songs of Syx changes its systems often enough that specific values age quickly, so nothing on this list depends on one. Every item asks you to read a number out of your own save rather than compare against a published constant. When a version moves the numbers, the checks still hold.

Which version this is written against

V0.71, the branch the community was posting from through July and August 2026, which is where the frustrated-colony threads behind this checklist come from.

Every item deliberately asks you to read a number out of your own save rather than compare against a published constant, so a later version moving the numbers does not invalidate the list. If a future version adds a balance we have not covered here, that is the one thing that would date this page — not a changed value.
