Quick answer: Detect and tag whether the game is modded on every crash report, and capture the active mods and load order, so you can separate base-game bugs from mod-induced ones. A thriving mod community is an asset, but unlabeled modded crashes pollute your data and waste your time chasing bugs that are not yours.
A modding community is one of the best things that can happen to a game, extending its life for years and deepening player investment. It is also a quiet threat to your bug data, because a modded game crashes in ways that have nothing to do with your code, and if those crashes arrive unlabeled they pollute your reports and send you chasing bugs you did not write. The key to collecting bug reports from a modded player base is separating the modded crashes from the real base-game issues, so your data stays clean and your effort stays focused.
Mods change what a crash means
When players can modify your game, a crash report is no longer guaranteed to be about your game. A mod can introduce its own bugs, conflict with another mod, or interact badly with your systems in ways the mod author did not intend. These crashes look like your crashes in the report, but the cause lives in code you did not write and cannot fix directly.
If you treat all crashes the same, a popular but buggy mod can flood your reports with crashes you spend days investigating before realizing they are not yours. The first principle of handling a modded community is that you must be able to tell, at a glance, whether a given crash came from a vanilla or a modded game, because that single distinction determines whether the crash is even your problem.
Detect and tag the modded state
The most important capability is detecting whether the game has been modified and tagging every report accordingly. Depending on your game, this might mean checking whether mod files are present, whether the game data differs from the shipped version, or whether your modding API is active. However you detect it, attach a clear modded-or-vanilla flag to every crash.
With this flag, you can filter your reports to vanilla crashes only and focus your debugging on the bugs that are actually yours. You can also look at modded crashes separately when you want to understand how mods interact with your game. The tag does not throw away the modded data, it just keeps it from contaminating your view of base-game stability, which is the data you most need to act on.
Capture the mod list and load order
For the modded crashes you do want to investigate, the active mods and their load order are essential context. Mod conflicts are a leading cause of crashes in a modded game, and they depend entirely on which mods are loaded and in what order. A crash report that includes the mod list lets you spot when a particular mod or combination is responsible.
Capturing the load order is what lets you and the modding community diagnose conflicts. When many crashes share a specific mod or a specific pair of mods, you have found the culprit, and you can either work with the mod author, document the conflict, or adjust your game to handle the interaction more gracefully. Without the mod list, a modded crash is an unsolvable mystery, and with it, it becomes a tractable conflict to resolve.
Support the modding community's own debugging
A healthy modding scene does much of its own bug triage, with mod authors fixing their own crashes. You can empower this by making your crash data and modded-state detection available to the community, so mod authors can see crashes involving their mods and fix them. This turns your modders into partners who handle the bugs in their own code.
Give mod authors the tools and context to diagnose their crashes, the stack traces, the mod list, the load order, and they will resolve issues you would otherwise have to triage and dismiss. A modding community that can self-diagnose keeps your bug reports cleaner and your game more stable, because the mod-induced crashes get fixed by the people who actually wrote them, rather than landing on your desk to be sorted out.
Setting it up with Bugnet
Add a custom field that flags whether the game is modded, and attach the active mod list and load order on modded reports. Bugnet stores these alongside the crash, so you can filter your dashboard to vanilla crashes for your own debugging and to modded crashes when you want to understand mod interactions, keeping the two cleanly separated.
Group crashes into occurrence counts within each category, so you see the true rate of base-game crashes uncontaminated by mod noise, and separately see which mods are causing the most modded crashes. This separation is what lets a game with a vibrant modding community maintain a clear, actionable view of its own stability, instead of drowning in crashes from code it did not write and cannot fix.
Decide your support boundary clearly
With modded and vanilla crashes separated, you can set a clear and fair support boundary: you fix base-game bugs, and mod-induced bugs are the responsibility of the mod authors, with your support being the data and tools to help them. Communicating this boundary clearly to your community prevents the resentment that comes from either over-promising support for mods or appearing to ignore modded players entirely.
Most modding communities understand and respect this boundary when it is stated honestly, because they know mods are unofficial extensions. The combination of clear communication and clean, separated data lets you support a thriving modding scene without it consuming your QA capacity. You get the longevity and engagement that mods bring, while keeping your own bug fixing focused on the game you actually shipped, which is exactly the balance a modded game needs to stay healthy.
A modded crash is not always your crash. Tag it, separate it, and keep your data clean.
