Bug Reporting for Games With In-Game Level Editors

An in-game level editor turns your players into level designers, letting them build, save, share, and play creations you never authored or tested. That generative power means editor bugs depend on the specific level a player made: a tool that misbehaves on one arrangement of objects, a level that loads broken, or a published level that plays differently than it did in the editor. The only reliable repro case is the level data itself. This post covers editor tool defects, save and validation, and the editor-to-play boundary, and how capturing the level and editor state turns user-generated chaos into loadable, fixable tickets.

Why level editor reports are different

The central challenge of an in-game level editor is that the content is authored by players, so the space of levels is unbounded and unique. A bug a player hits may depend on an arrangement of objects, triggers, and parameters that no one on your team would ever build, which means a description can never carry enough to reproduce it. Like other user-generated-content systems, the artifact is the repro case, and the reporting flow has to prioritize capturing the level data over asking the player to narrate steps they may not even remember taking.

Editor bugs also span three distinct contexts that behave differently: editing the level, play-testing it inside the editor, and playing a published version someone else made. A defect might appear only in one of these, for example a level that edits and tests fine but breaks when published and loaded by another player on a different game version. Because the same level data flows through all three, a useful report has to record which context the bug occurred in, alongside the level data and editor state, so your team reproduces it in the right mode rather than the wrong one.

Editor tool defects

The editing tools are the player's interface and a rich source of bugs. Placement tools can snap objects to the wrong grid cell, refuse to place where space clearly exists, or overlap objects that should not coexist. Selection, copy-paste, undo, and redo are especially dangerous: an undo that does not fully restore state, or a paste that duplicates an object's id, can quietly corrupt a level in ways the player only discovers later. Reporting these needs the active tool, its settings, the target cell or coordinates, and the objects the tool acted on, so an engineer can reproduce the exact operation.

Object configuration adds another layer. Editors let players set parameters on objects, wire triggers to actions, and link entities like doors to switches, and the validation rules for these are easy to get wrong. A trigger that links to a deleted target, a parameter that accepts an out-of-range value, or a one-way link that should be two-way all produce levels that behave unpredictably. To report them well you want the configuration of the affected objects and the links between them, so your team can recreate the exact logic graph rather than guessing how the player connected the pieces together.

Save, validation, and the play boundary

Saving and loading level data is the backbone of an editor, and as the level format evolves across updates it becomes a major bug surface. A level must serialize every object, transform, parameter, and link and restore them exactly, including across versions. Bugs include levels that load with missing objects, links that do not survive a save, or levels authored on an old version that fail to load after an update. Validation is the other half: a level that passes the editor's checks but is actually unwinnable, or one rejected at publish for a rule it does not violate. Reports must include the level data and the format version that wrote it.

The boundary between the editor and actual play is where many of the worst bugs hide, because the editor and the runtime can interpret the same level data differently. A level that looks correct in the editor might spawn the player out of bounds at runtime, fail to trigger a scripted event, or be impossible to complete because a jump is one pixel too far in the play physics. Capturing whether the bug occurred while editing, play-testing, or playing a published level, along with the player or spawn state at the moment of failure, tells your team which interpretation of the data went wrong.

Setting it up with Bugnet

Bugnet is a strong fit for the content-driven reporting an editor requires. Wire the in-game report button so that when a player files a report it attaches custom fields for the active editor tool and its settings, the target cell or coordinates, the selected object count, the level format version, and the context, editing, play-testing, or playing a published level. Because Bugnet stores these as searchable fields on one dashboard, you can filter for every report from a specific tool or format version and find the shared defect instead of reading scattered, level-specific complaints one at a time.

For the bugs that depend on the level itself, attach the serialized level data directly to the report as a file attachment so your team can load the exact level that broke. Occurrence grouping folds duplicate reports of the same tool or validation bug into one counted issue so the widespread problem rises in triage, while level-specific reports stay individually inspectable. With labels for tools, save-load, validation, and play-boundary, a developer opening an editor report sees the tool and context state and can load the attached level to reproduce a broken trigger or an out-of-bounds spawn directly.

Building a reporting workflow

Make level capture the default. Add a report button to the editor and to the play view that automatically bundles the current level data, or the relevant portion, with the report so players never have to manually export and upload a file. Critically, capture the context flag, editing, testing, or playing published, since the same level can behave differently in each and your team needs to reproduce in the right mode. For runtime failures, capture the player and spawn state at the moment of the bug so an out-of-bounds spawn or a missed trigger is fully described.

For triage, lean on the attached levels and captured fields. Build a regression library of player levels that exposed bugs and reload them against every new build to confirm fixes and catch format regressions, which matters greatly as your level format evolves and you must keep older shared levels playable. Cluster reports by tool, validation rule, or context, and prioritize anything that corrupts levels or breaks published content, since those bugs ripple across everyone who plays the shared creation, not just the author.

Make it part of how you ship

In-game level editors let players author and share levels you never tested, so editor bugs depend on the specific level data and cannot be reproduced from words. Bake level attachment and the context flag into your report button from the start, well before your format begins to drift across updates and before a thriving community of shared levels makes format compatibility critical.

Treat each broken-level report as the only practical way to debug content you could never enumerate, because players will build and share things you never imagined. Capture the editor tool and context state, attach the level data with its format version, and route it all into one dashboard with a regression library on your side. Instrument your tools, level format, and validation now, and your editor reports will turn otherwise unreproducible, level-specific failures into loadable, fixable tickets that protect both authors and the players who play their levels.

In an editor the level is the repro case. Attach the level data and the context flag, and user-generated chaos becomes loadable, fixable tickets.
