Mutant Plants Base Defense Expired Codes Tracker
Rainbow Isle Base has not shut down the August 2026 set yet — still Verify every string in-game.
Current status (August 2026)
As of the mid-August 2026 code roundups — including the Aug 11 BUGFIX0983 Shadow Grenades drop — no Mutant Plants Base Defense codes are confirmed expired. Developers appear to keep older RELEASE*, BUGFIX*, and UPD* strings live alongside newer packs.
That can change overnight. This page exists so you have a place to park retired strings when Rainbow Isle Base finally disables them, without polluting the Active Codes table.
Working set reminder
Still redeem these through Shop → Codes → Verify unless your client rejects them:

When a code “expires” for you personally
A code can fail because:
- It is globally disabled (true expiry).
- You already redeemed it on this account.
- You mistyped case or added spaces.
- You are on a stale server during admin events — rejoin if developers ask.
Only case 1 belongs on this expired list. Cases 2–4 are account or session issues.
How we will list future expired codes
When a string dies, this page will show:
| Code | Last known reward | Notes |
|---|---|---|
| — | — | No expired codes yet |
Until then, treat chat claims of “dead codes” as unverified unless your own Verify rejects a never-claimed string.
Hygiene habits
- Keep a personal redeemed log.
- Recheck Active Codes after every patch note (UPD-0.5, Patch Notes).
- Prefer Discord discovery plus in-game Verify over random screenshots (How to Get New Codes).

No expired codes today does not mean forever. Bookmark both Active and Expired pages so reward tables stay honest.
Why an expired tracker still matters while the list is empty
Empty expired pages look useless until the first string dies. When Rainbow Isle Base disables a RELEASE* or BUGFIX* code, players flood chat with conflicting screenshots. A dedicated expired tracker keeps Active Codes clean and gives you a place to record last-known rewards for historical reference.
Until that day arrives, use this page as a checklist companion:
- Open Active Codes.
- Redeem anything you have not claimed.
- If Verify rejects a never-claimed code after careful retype and a fresh join, note it here mentally and watch for wiki updates.
- Do not delete working codes from your personal notes based on a single friend saying “it died.”
Distinguishing rumor expiry from real expiry
Real expiry usually shows as consistent Verify failures across fresh accounts. Rumor expiry shows as one streamer failing a code they already redeemed last week. Always ask: “Has this account ever claimed it?” before you archive a string.
Also check capitalization. bugfix0983 is not BUGFIX0983. Case mistakes create fake expired lists. Redeem path reminder: How to Redeem Codes.
Planning around future retirements
Assume grenade codes can rotate after major UPD drops. Bank Flame, Frozen, and Shadow packs when they are live instead of waiting for a perfect wave. Fruit codes should land on keepers quickly once the board is stable (Fruits and Mutations). Gem codes should hit Upgrade Zone floors before Luck spam (Base Upgrades).
Community hygiene
Share only codes you personally Verified. Do not paste expired rumors as “working.” Point friends to Active Codes and this Expired Codes page instead of screenshot chains. Discovery habits: How to Get New Codes. Discord and Roblox links: Wiki / Links.
Session checklist including expiry awareness
- Active list opened today?
BUGFIX0983claimed if available?- Any Verify reject on a never-claimed string?
- Inventory counted after successful redeems?
- Spending plan ready before the next wave?
That checklist keeps both Active and Expired pages honest while Rainbow Isle Base still keeps the August 2026 set alive.
Frequently Asked Questions
Quick answers to the most common questions.
Are any Mutant Plants Base Defense codes expired?
As of mid-August 2026, no codes are confirmed expired. Always trust in-game Verify.
A code failed but friends say it works — is it expired?
Maybe you already claimed it, mistyped it, or need a fresh server. Check those before calling it expired.
Where do new codes appear when old ones die?
On Active Codes first. Retired strings move here once Verify consistently rejects never-claimed accounts.
