How to Fix a Game That Crashes Only on Certain Levels

A crash confined to certain levels is a content problem in those levels. Knowing which level and comparing it to working ones finds it. Here is how.

How to fix it

1. Capture the level in the crash

Record which level was active at the crash. A crash that only ever happens on specific levels localizes the bug to their content immediately, rather than to the engine or shared code.

2. Compare failing and working levels

Diff the crashing levels against ones that work. A shared difference — a particular asset, a setup, an entity count — is likely the cause. The pattern across failing levels points at it.

3. Fix the content or budget

The cause is usually a broken reference, an unhandled setup, or a memory or object-count budget those levels exceed. Fix the specific content issue, then confirm the level loads cleanly.

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 your game 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.
