What causes population outgrowing available housing?

Population growth is driven by a flat rate independent of vacancy, so newcomers keep arriving even when every home is occupied, producing a permanent homeless backlog.

How do I catch this when it only happens for some players?

Capture it automatically from the player's device with the full stack trace, the device and OS, the build, and a breadcrumb trail of what they did. That turns a vague complaint into a specific, reproducible issue you can fix without owning the hardware it happens on.

How to Fix Population Growing Faster Than Housing Can Be Built

Quick answer: Gate immigration on available housing capacity, queue arrivals against vacancies, and slow growth as vacancy approaches zero instead of pushing past capacity.

When new citizens pour in but there is nowhere for them to live, growth is not respecting housing supply. The sim adds people first and looks for homes second. Tie arrivals to vacancy so the city grows only as fast as it can house people. Here is how.

How to fix it

1. Gate immigration on vacancy

Before admitting a newcomer, check that a vacant home exists and reserve it. With no vacancy, hold or reject the arrival instead of creating a homeless agent that clogs the simulation.

2. Scale growth rate by vacancy

Let the growth rate fall toward zero as occupancy nears 100 percent and rise when vacancy is high, so population tracks housing supply smoothly instead of overshooting.

3. Queue arrivals against new homes

Maintain a waiting queue of would-be immigrants and admit them as homes are completed, turning raw growth pressure into a visible demand signal the player can respond to.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.

Reproduce it once with full context and the fix writes itself. The hunt is the expensive part.
