Roblox Build Game Crashes
For a crash during a playable Build game, locate the gameplay transition that was interrupted: start, pickup, outcome, scene change or retry. Preserve the incident already observed instead of repeatedly forcing it. A clear transition record is more useful than an unsupported claim about memory or generated code.
Symptom
An already playable generated game exits during a particular gameplay action or phase transition.
Immediate action
Write the precondition, selected action and last visible response from the incident already observed.
Diagnostic branches
- The exit follows a pickup, reward or completion chain.
- List its observed stages and stop before assuming which hidden operation failed.
- A retry or scene transition precedes the exit.
- Include the old round state and whether the destination scene ever became visible.
- An explicit access or moderation notice is shown instead of an unexplained exit.
- Preserve that notice and use its legitimate assistance path.
- The game remains visible but no longer responds.
- Use freeze diagnosis while retaining the same event trace.
Least-destructive change
Use the existing transition evidence and avoid deliberate crash loops or repeated reward activation.
Retest
- The report states the round precondition needed to understand the action.
- Every stage marked observed was actually visible before the exit.
- A later starting state is not automatically called lost stored progress.
- Reproduction is skipped when it risks work or paid/reward side effects.
Escalation
Provide official assistance the identified game's transition trace and any exact error. An ordinary later occurrence can supplement the record, but no forced repeat, purchase or internal-cause diagnosis is required.
Working notes
Begin with the precondition immediately before the exit. Record the round phase, active objective and relevant state already visible. Then record the action and the last response before the game closed. This separates a crash on entering a scene from a crash after its first interaction, without making the reader reproduce either.
Split a compound event into observable stages. For a pickup followed by a reward and a new scene, note whether the pickup vanished, the counter changed, reward feedback appeared or the transition began. An unobserved later stage remains unknown. The last visible stage is a reporting boundary, not proof that it caused the exit.
On a normal later return, inspect the same creation and distinguish its current round state from what was visible before the incident. If a reward-related interaction was involved, avoid repeatedly activating it to test whether rewards are duplicated. No purchase or live-player transaction is needed for this investigation.
Choose the report destination from the outcome. A visible moderation or access notice belongs to that official workflow; a whole-app exit can include the app-level crash record; a game that stays open but freezes needs the narrower freeze investigation. Keep the gameplay transition as the central evidence instead of collecting every unrelated device setting.
Examples
- Interrupted-chain example: collectible disappears → score visibly changes → result panel starts to appear → game exits before the next scene is visible. Report those observed stages and leave the new-scene state unknown; do not label the reward logic as the proven cause.
- Restart-specific incident: a completed round remains visible until its restart control is selected, then the game exits rather than returning to the initial state. The reproduction description needs the completed-round precondition, not just the word crash.
- Post-return comparison: before exit, the score display changed; after returning, the existing creation opens with its normal starting score. This describes two visible states and does not by itself establish that stored progress was lost.
