Should I close a bug report I cannot reproduce?

No, flag it as needs-info or watching and let occurrences accumulate. Most unreproducible bugs are real but environment-specific. The pattern across several reports, same GPU, same OS, same locale, is often the reproduction step you were missing. Closing it just invites an angrier re-report.

How do I reproduce a bug that only happens on a player's machine?

Capture the environment automatically instead of asking them to trigger it on demand. Logs, device specs, graphics settings, and the recent action sequence reveal what your clean test rig cannot. An SDK that attaches this context to each report turns a vague complaint into a specific, actionable pattern.

What do I tell a player when I cannot reproduce their bug?

Believe them and say you are still narrowing it down, not that it works on your end. "I have not triggered it yet, so I have flagged it to watch and your logs will help" keeps the player engaged as a partner instead of feeling accused of making it up.

How to Respond to Bug Reports You Cannot Reproduce

Quick answer: Believe the player, gather environment and log data instead of asking them to reproduce on demand, and keep the report open as a watch item rather than closing it. Most unreproducible bugs are real and platform-specific, not imaginary.

"Cannot reproduce" is the most overused and most damaging status in bug tracking. To the developer it means "I tried and it worked fine." To the player it means "you think I am lying." The truth is that the vast majority of unreproducible reports are real bugs that depend on hardware, OS, settings, or timing you do not have on your machine. The job is to gather enough context to see what the player sees.

Start by Believing the Player

The player experienced something. Your inability to recreate it on your dev machine says more about how different their environment is than about whether the bug is real. Responding with "works on my end" tells the player their report was wasted; responding with "I have not been able to trigger it yet, help me narrow it down" keeps them engaged as a partner.

Many of the worst bugs only manifest on specific GPUs, OS versions, locale settings, or under particular timing. Your clean test rig is exactly the environment least likely to reproduce an edge-case bug.

Gather Context Instead of Demanding Repro

Asking a player to reproduce a bug on command rarely works, especially for intermittent ones. What works is capturing the environment automatically when it happens. Logs, device specs, OS, graphics settings, and the recent sequence of actions tell you what your machine cannot. An SDK that attaches this context to every report turns "cannot reproduce" into "oh, it only happens on integrated graphics with vsync off."

Bugnet's reporting captures logs, device context, and a stack trace automatically with each crash or report, so even a one-line player complaint arrives with the diagnostic data you need. Often the pattern across several unreproducible reports, all the same GPU vendor, all the same locale, is the reproduction step you were missing.

Keep It Open as a Watch Item

Do not close an unreproducible report as invalid. Tag it as needs-info or watching and let occurrences accumulate. The second, fifth, and tenth report of the same thing build the pattern that finally cracks it. A bug closed prematurely just gets reported again by someone angrier.

Tell the player what you are doing: "I have not reproduced this yet, so I have flagged it to watch, your logs are attached and they will help if it happens to others." That keeps the report alive in your system and keeps the player feeling useful rather than dismissed.

"Cannot reproduce" usually means "I do not have your hardware," not "this is not real."
