A rollback plan is a product feature A LiveOps event can fail without any code deployment: a reward table is wrong, a promo code becomes too generous, an expiry window is set in the wrong time zone, or a remote setting activates an unfinished event. If the only response is “ship a hotfix,” the team has already lost the cheapest recovery option. For Roblox projects, the useful order is: contain, inspect, repair, then re-enable. 1. Keep the client out of the authority path The client can render event copy and request a claim. It should not decide whether a promotion is valid, what reward it grants, or whether an event is active. Those checks belong on the server, where the active configuration and a last-known-good version can be enforced consistently. 2. Make event configuration versioned Each event definition needs an identifier and version. On activation, record which version is in use. On an incident, disable that version first instead of overwriting it in place. That preserves the evidence needed to answer: who was affected, which reward path ran, and what is safe to restore. 3. Treat reward claims as idempotent A retry must not mint the reward twice. A compact event ledger keyed by player, event, reward, and claim identifier gives a recovery path even when Roblox networking retries or a server restarts during a grant. 4. Rehearse the smallest safe action A practical test before launch is not only “does the event work?” It is: Can the server switch the event off? Does a disabled event reject claims cleanly? Can an existing claim be replayed without duplicate rewards? Can the team identify the active version and affected players? A versioned server-side runtime makes that checklist much easier to maintain.

It is to ensure a bad configuration can be contained before it turns into a player-state or economy problem—and that the subsequent repair is deliberate and reviewable.
