How do I figure out what an update broke?

Compare the new version against the previous one: the crashes and problems that appeared or surged on the new build are what the update broke. An update that breaks your game introduced a regression, a change that made something worse, and the way to find it is per-version comparison: check crash rate and new crashes per version, and the crashes that appeared on the new build (that were not there on the previous one) are the regression the update introduced. Group those new crashes by signature and rank by affected players to identify the specific regression (the crash driving the breakage), and read its captured stack trace, device, and version to find the cause (the code path that broke, the conditions). This pinpoints what the update broke, the specific crash, the code path, and the conditions, rather than leaving you with a vague update made things worse. So you figure out what an update broke by comparing the new version against the previous one (per-version data showing the crashes the update introduced), identifying the specific regression (signature grouping and impact ranking), and reading its captured context (stack trace, device, version) for the cause. Bugnet tracks crashes per version with signature grouping and full context, so you can compare builds, see exactly which crashes the update introduced, and read why, turning a broken update into a precise diagnosis of what changed for the worse, then roll back or hotfix and verify per version that stability returns.

Should I roll back an update that broke my game?

Roll back if the update broke something serious and a fix will take time; hotfix if you can fix the regression fast. The decision depends on how badly the update broke things and how quickly you can fix it. If the update introduced a serious regression (a game-breaking crash or widespread problem) and you cannot fix it quickly, roll back to the previous stable build, this immediately undoes the breakage, returning players to a working version while you fix the regression without time pressure. If you can identify and fix the regression fast (the captured context points clearly at the cause), hotfix, ship a targeted fix that resolves the regression while keeping the rest of the update's improvements. To decide, you need to know the regression's severity (how many players it affects) and have the context to gauge fix speed (the stack trace showing the cause), both from capturing crashes with context and ranking by impact. So roll back an update that broke your game when the regression is serious and slow to fix (undo the breakage now), and hotfix when you can fix it fast (resolve the regression without losing the update). Either way, verify per version that stability returned, the rollback restoring the previous build's crash rate, or the hotfix dropping the regression's crashes on the new build. Bugnet's impact ranking shows the regression's severity (informing the call), its captured context helps you gauge and execute a fast fix, and its per-version tracking confirms the action worked, so you can make and verify the roll-back-vs-hotfix decision with data rather than guesswork.

How do I prevent updates from breaking my game?

Catch regressions before and right after release: test the changed areas on real devices, monitor crash rate per version after shipping, and gate releases on stability so an obviously-broken build does not go wide. Updates carry inherent regression risk, new code is the least-tested code and can break things that used to work, so you cannot eliminate the risk, but you can catch regressions fast. Before release, test the areas the update changed (especially on real devices, where regressions that hide on your dev machine surface). After release, monitor crash rate per version so a regression that slipped through is caught within minutes (a crash spike on the new build) rather than from player reports days later, letting you roll back or hotfix before it spreads. And gate releases on stability: before an update goes wide, check that it is not obviously worse than the previous build (per-version crash rate), and do not ship (or do a staged rollout) if it is. So you prevent updates from breaking your game by testing changed areas on real devices (catching regressions before release), monitoring crash rate per version after release (catching regressions fast), and gating on stability (stopping obviously-broken builds), the combination that catches regressions before they reach players in numbers. You cannot prevent every regression, but you can catch them fast, which is what limits the damage. Bugnet's per-version crash tracking with spike alerts is central to this, it catches a release-introduced regression within minutes (the new build's crash rate climbing) so you can reverse it before it spreads, and lets you gate releases by comparing a new build's stability against the previous one, turning broken updates from a recurring surprise into a caught-and-reversed event.

What to Do When an Update Breaks Your Game

Quick answer: Compare the new version against the previous one to see what broke, identify the regression from captured crashes and reports, and roll back or hotfix while verifying per version that stability returns.

When an update breaks your game, you have a regression, the release made something worse. The fastest path back is to see exactly what the update broke and reverse it. Here is what to do when an update breaks your game.

Compare the New Version Against the Previous One

An update that breaks your game introduced a regression, so the first step is comparing the new version against the previous one to see what changed for the worse. Check crash rate and new crashes per version: the crashes that appeared or surged on the new build are what the update broke, isolating the regression to the release.

Bugnet tracks crashes per version, so you can compare the new build against the previous one and see exactly which crashes the update introduced. That comparison is how you pinpoint what the update broke, the new or surging crashes on the new version, rather than guessing at a vague post-update problem.

Identify the Specific Regression and Its Cause

Pinpoint what broke: group the new crashes by signature and rank by affected players, and the regression stands out, the crash that appeared on the update. Its captured stack trace, device, and version reveal the cause, the code path that broke and the conditions, so you know the specific change to fix or revert.

Bugnet groups crashes by signature with full context, so the regression the update introduced is identifiable with its stack trace and conditions. That tells you the specific thing the update broke and why, turning a broken update into a concrete fix, the exact crash and code path the release regressed.

Roll Back or Fix the Regression, Then Verify

Reverse the regression: roll back the update if it broke something serious and a fix will take time, or hotfix the specific regression if you can fix it fast. Then verify per version that the new build's stability matches the pre-update level, confirming the regression is resolved rather than assuming.

Bugnet tracks crash rate per version, so after rolling back or hotfixing you can confirm the regression's crashes stopped on the new build and stability returned. This verifies the update is no longer breaking your game, you see the per-version data return to normal rather than hoping the fix held.

When an update breaks your game, compare the new version against the previous one to see what broke, identify the regression from captured crashes, and roll back or hotfix while verifying per version. A broken update is a regression.
