Quick answer: Track the crash rate (or crash-free sessions) per build, alert on a spike when a new version rolls out, and compare the new build against the previous to catch regressions immediately.

A crash spike after release is invisible without per-version monitoring. Watching the crash rate catches it. Here is how.

How to fix it

1. Track crash rate per build

Measure crashes (or crash-free sessions) tagged by build version. This gives you a baseline and lets you see when a new release deviates from it, rather than relying on anecdotes.

2. Alert on spikes

Set an alert for when the crash rate rises sharply, especially as a new version rolls out. Catching a spike within hours lets you halt the rollout or hotfix before it reaches everyone.

3. Compare against the previous build

When a new build's crash rate exceeds the previous one's, you have a regression. Compare versions directly so you know the release caused it, and which crash signature is new.

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.

Ship the fix, watch the signature disappear from the next build. That's how you know it's really gone.
