Every piece of software you have ever used shipped with bugs still in it, and the people who made it knew about many of them. That sounds like negligence, but it is the opposite: a deliberate, carefully reasoned choice about where to spend a limited pool of time and effort. No team can fix everything, so the real skill lies in deciding what to leave alone.
Behind that choice sits a whole discipline, with its own vocabulary and its own quiet logic. Once you see how developers sort the bugs worth fixing from the ones worth ignoring, the occasional glitch in your favourite game or app starts to look less like laziness and more like triage under fire.
You Can’t Fix Everything
The hard reality of software is that bugs always outnumber the hours available to fix them. A big project can log thousands of them, arriving faster than any team could ever clear, so treating every one as equally urgent would mean grinding to a halt and shipping nothing at all. Choices have to be made, and made constantly.
This forces developers into ruthless prioritisation, spending their effort only where it does the most good and consciously accepting the rest. It is not so different from how any careful business decides which problems truly threaten what its customers value most.
The same logic runs through any service people rely on. At an online casino, someone claiming a slotozen casino no deposit bonus cares about the variety of slots, the real chances of winning, the promotions and, above all, that deposits and payouts work every single time. So the one class of fault an operator can never wave through is anything touching a player’s money or the fairness of a game, however tempting it might be to leave a harmless cosmetic glitch for another day. That instinct, protect what matters most and let the trivial wait, is exactly what bug triage is built to formalise.
How A Bug Gets Judged
When a bug is reported, it does not go straight to a programmer to be squashed. It enters a sorting process, often called triage, where its fate is decided in three broad stages. Each one strips away a little more uncertainty until the team knows not just what the bug is, but whether it is worth their time at all. Understood in sequence, the process explains almost every fix-or-ignore decision ever made.
Logged And Measured
The first stage is simply capturing the bug clearly, because a vague report is almost useless. The team needs to know exactly what goes wrong, how reliably it can be reproduced, and how many people it is likely to hit. A bug that happens every time for everyone is a very different creature from one that appeared once, for one player, under conditions nobody can recreate. If an issue cannot be reproduced at all, it often cannot be fixed, and it drifts to the bottom of the pile by default. Timing matters here too, since the earlier a bug is caught the cheaper it is to put right, and by 2026 many teams lean on automated tools that predict how serious a fault is likely to be from the part of the code it touches, saving hours of manual sorting.
Scored On Severity And Priority
Next the bug is measured against two separate yardsticks that are easy to confuse. Severity asks how much technical damage it does, from a harmless visual quirk up to a full crash or lost data. Priority asks a quite different question: how soon it needs fixing, judged by its effect on the business, the release date and the people using the product. The two do not always agree, and that gap is the heart of the whole art. A severe bug buried where almost no one will meet it can wait, while a trivial one sitting on a screen every customer sees may jump straight to the front of the queue.
The Fix, Defer Or Ignore Call
With the bug logged and scored, the team makes the actual decision, and it is rarely a simple yes or no. Some bugs are fixed at once, some are deferred to a later update, and some are formally set aside with a label like will-not-fix or by-design, meaning the team has looked at them and consciously chosen to live with them. A decisive part of this call is the risk of the repair itself, since changing code to fix one thing can easily break another, and a fix that threatens more damage than the bug it addresses is often wisely left undone.
What Tips The Decision
The factors that push a bug up or down the list are consistent enough that you can lay them out plainly. What matters is never the bug in isolation, but its impact set against the cost and risk of dealing with it. The table below shows how severity and priority can pull in completely different directions for four typical bugs.
|
A bug |
Severity |
Priority |
|
Crash in a menu nobody visits |
High |
Low, fixed later |
|
Typo on the checkout button |
Low |
High, fixed at once |
|
Save file corrupts on quitting |
High |
High, drop everything |
|
Odd shadow on a distant wall |
Low |
Low, may never be fixed |
Read across the rows and the logic is clear: a bug’s technical nastiness is only half the story, and its real fate is decided by how many people it touches and how much it threatens what they care about. This is why a spectacular-sounding crash can be quietly shelved while a humble typo gets fixed within the hour.
The Bugs Left In On Purpose
Strangest of all are the bugs developers could fix but deliberately do not, because the players have come to love them. A glitch that lets a character clip through a wall or vault across a level can become a treasured part of a game’s culture, embraced by speedrunners and casual players alike, and quietly patching it out can cause more upset than leaving it in.
More often, though, a bug survives for duller reasons, and it helps to know which ones tend to earn a permanent reprieve:
- It is nearly impossible to reproduce — a fault no one can reliably trigger is a fault no one can confidently fix, so it lingers.
- It affects almost nobody — an edge case that hits a tiny fraction of users rarely justifies the effort of a proper fix.
- A workaround already exists — if players can easily sidestep the problem, the pressure to solve it properly drops away.
- The fix is riskier than the bug — when a repair might destabilise something important, living with the flaw is the safer choice.
None of these is an admission of defeat, but a calculated judgement that the cure would cost more than the disease. The art of shipping software is knowing exactly which flaws you can responsibly carry.
The Discipline Of Letting Bugs Live
Developers decide which bugs to fix and which to ignore through triage, a disciplined process of logging each fault, scoring it on how much damage it does and how urgently it matters, and then weighing the cost and risk of a fix against the harm of leaving it be. Severity is only the start; what really decides a bug’s fate is who it affects and what it threatens, set against the price of putting it right.
Far from carelessness, ignoring the right bugs is what makes finishing anything possible at all. The next time you meet a glitch that has clearly been left in for years, it is worth considering that somewhere a team looked at it, weighed it honestly, and decided your time was better served by everything they fixed instead.
FAQ
Why do developers leave known bugs in software?
Because no team has the time to fix every bug. They triage, focusing effort on faults that do the most harm to the most users, and consciously accept minor or rare ones, since fixing everything would mean never finishing the product at all.
What is the difference between severity and priority?
Severity measures how much technical damage a bug does, while priority measures how soon it should be fixed given business and user impact. A severe bug few people hit can be low priority, and a minor but very visible one can be high.
How do developers decide which bugs to fix first?
They weigh how many users a bug affects, how often it occurs, whether a workaround exists, and how risky the fix is. Bugs threatening money, safety or trust are fixed first, while rare cosmetic ones wait or are ignored.
Why are some game bugs never fixed?
Some are too rare or minor to justify the work, and others are left in on purpose because players enjoy them. A beloved glitch used by speedrunners, for instance, is often kept rather than patched away.
