Plan and test game mechanics

A mechanic needs an observable rule: an action, a change in state and feedback to the player. Before adding more systems, test whether the first action, win condition and restart work together. The existing guides below provide the starting workflow and debugging checks.

Prepare a game for publishing

Publishing starts with a game that can be tested, understood and maintained. Check the available creator controls, audience settings and safety requirements before a release. Use the publishing guide for the sequence, and the troubleshooting guide for an actual blocked step.

Roblox Build Tab Disappeared

If a Build entry you previously used has disappeared, preserve the last confirmed access and the current navigation state. Verify that the account and app surface match before calling it a regression. A vanished entry alone does not establish a ban, rollout reversal or lost project.

Symptom

A previously observed Build navigation entry is now absent.

Immediate action

Record the last confirmed successful access and current navigation before changing the account or project.

Diagnostic branches

Prior access belongs to another account or is only assumed.: Use ordinary missing-feature triage or the account-comparison guide.
The same account and surface previously had the entry.: Record a genuine before/after navigation change and known intervening conditions.
The entry still exists but a requirement changed.: Use changed-access diagnosis rather than reporting a disappeared tab.
The entry remains absent after documented checks and reopening.: Prepare a redacted regression record without guessing a backend reason.

Least-destructive change

Retain project identities and compare navigation states without clearing data or creating replacements.

Retest

The earlier successful action is actually known.
Current and prior account/surface context are comparable.
Project loss is not inferred from entry visibility alone.

Escalation

Provide Roblox Support the last confirmed access, current state and known changes. Report an unexplained regression rather than labelling it a ban, experiment or rollout rollback without evidence.

Working notes

Use a real earlier observation as the baseline. A remembered announcement or another person's screenshot is not evidence that this account had the entry. If you cannot establish prior access, use the ordinary missing-feature path rather than building a history around an assumption.

Record what changed between the observations only when known: the signed-in account, device, app version, location context or a displayed requirement. Do not fill the gap with a guessed rollout explanation. A coincident update or trip does not by itself establish the cause.

Keep project visibility separate from navigation visibility. An absent entry does not demonstrate that a created game was deleted. Preserve any existing project identity or published destination; do not create a replacement project simply to test whether the original still exists.

After checking the documented conditions, use the official reopen path as a comparison point. If the entry remains absent, preserve the before/after record for assistance. Repeatedly reopening without a relevant state change adds little evidence and should not replace a precise report.

Examples

Regression record: last confirmed date and surface / action successfully completed then / current account label / current navigation / known intervening change / reopen outcome. Unknown historical details stay unknown.
Not a confirmed regression: a friend previously showed the entry on another account. This establishes a comparison question, not disappeared access for the current account.
Separate asset question: the tab is absent, but a previously recorded public destination still exists. Keep those observations together without interpreting navigation absence as project deletion.
