Upgrade Does Not Work in Roblox Build
An upgrade can fail at eligibility, activation, ownership display or its promised effect. Inspect those boundaries separately using an existing non-paid prototype state. Do not buy a real product again to diagnose it, and do not treat a changed label as proof that the gameplay benefit was applied.
Symptom
An available or activated upgrade does not produce the observable benefit promised by its design.
Immediate action
Identify the promised effect, eligibility and lifetime without initiating another real purchase.
Diagnostic branches
- The intended prerequisite is not met.
- Inspect the eligibility explanation rather than claiming an activated benefit failed.
- Activation is not acknowledged or its outcome is uncertain.
- Preserve that state and avoid repeated paid actions.
- Ownership feedback changes but the comparable gameplay effect does not.
- Request agreement between the promised effect and its observed action.
- The benefit works but survives or disappears at the wrong boundary.
- Correct the stated lifetime without inventing permanent persistence.
Least-destructive change
Use existing non-paid prototype observations and isolate the failing benefit instead of stacking more purchases or tiers.
Retest
- An eligible non-paid test activation produces the stated observable effect.
- Ineligible and already-owned states do not create an unintended repeated deduction.
- The benefit's duration matches the explicit design boundary.
Escalation
Route an actual paid entitlement or transaction problem through the relevant official support process with existing evidence. This gameplay checklist does not verify purchases, promise refunds or certify a monetization implementation.
Working notes
Write the promised change in observable terms and note its intended scope. A movement upgrade should affect the defined movement test; an output upgrade should affect the specified production action. Permanent ownership, an active-round effect and an unlock for a later stage are different promises that must not be silently merged.
Establish whether the prerequisite was met and whether activation was acknowledged. In a prototype using only earned test resources, compare the displayed requirement with the available balance and resulting deduction. If a real Robux purchase is involved, stop diagnostic buying and preserve the receipt or status already available through official channels.
Compare the same effect before and after the acknowledged upgrade. Hold the relevant action and scene steady. A larger level number with unchanged observed output is a reportable display/effect discrepancy; it does not prove which internal value failed or authorize another purchase.
Inspect the duration of the effect according to the written design. If a retry clears a benefit that was intended to last through the session, record that lifetime mismatch. Do not promise persistence across leaving the game merely because a within-session test worked. Fix the single benefit before adding more upgrade tiers.
Examples
- Prototype upgrade trace: earned-resource requirement met → activation acknowledged → test resource balance changes → ownership label changes → the same production action is observed. Each boundary gets its own result rather than a single works checkbox.
- Proposed repair for a non-paid test upgrade: Preserve the current resource cost and eligibility rule. After acknowledged activation, apply the stated output increase to the existing production action and show its active state. Do not deduct again when the benefit is already owned under this design.
- Lifetime mismatch: the upgrade affects output in the current attempt but disappears after retry, although the written plan says it should last for the session. This is a retention decision to correct, not evidence that permanent account storage exists.
