Ratatan · Achievement troubleshooting
Ratatan Early Access achievements not unlocking: what needs repeating?
On this page
The developer distinguishes an unlock bug from missing historical progress. A fix is planned for some achievements, but eight named goals did not record Early Access progress and must be met again.
Check the list before repeating a long objective: waiting for a patch and redoing an unrecorded goal address different situations.
The eight Early Access exceptions
These are the names and conditions in the developer’s notice, not the complete achievement catalogue.
| Achievement | Condition to meet again |
|---|---|
| Front Line Fashion | Equip an accessory on a cobun and embark on an adventure. |
| Indestructable | Clear World 5 without being knocked down once. |
| Ratatan Legend | Defeat 100 Dark Ratatan in total. |
| My First cobun | While playing solo, deploy with exactly three cobun and clear World 5. |
| Karuta Collector | Obtain Ratakaruta 300 times. |
| Rhythm Paradise | Land 100 Just Judgment rhythm commands. |
| Ratatan Master | Clear World 5 using all eight Ratatan. |
| The Goddess Knows | While playing solo, clear World 5 with an Oath Level of 5 or higher. |
Choose your next action
- On the list: plan a new attempt that satisfies every clause, including solo play, deployment size or Oath Level when specified.
- Not on the list: do not assume it must also be repeated. Read the latest patch notes before committing to a long replacement run.
- A new attempt also failed: record the installed version, platform, exact achievement and the conditions you satisfied.
- After an update: check the actual unlock state; a completed download alone is not evidence that your missing achievement was awarded.
Read the small conditions before committing
Make a short checklist before starting. A condition that names a solo run needs its own record. A deployment-size condition is worth checking before entry. For a multi-character objective, keep a character-by-character list rather than relying on memory.
This is a planning method, not an extra requirement. Do not add restrictions that the stated goal does not contain, or assume every achievement uses the same mode. If your installed game’s description differs from the announcement, keep a screenshot of both and include the version when investigating.
Keep repeat attempts separate from patch expectations
Maintain two lists: objectives you intend to meet again, and objectives you are waiting to recheck after a relevant patch. That prevents one failed unlock from turning into the unsupported conclusion that all progress has disappeared.
If the next attempt still does not unlock, keep the result and the setup that produced it. Repeating the same long run without recording what changed provides little new information. Do not delete a save merely because an achievement is absent.
Prepare a useful report
Record the exact achievement name, platform, installed version, whether the attempt occurred before or after full release, and the conditions you can verify. Mark unknown details as unknown. Use the developer’s official feedback route and review any requested attachment before sending it; account credentials do not belong in a public report.
Progression at the Bonboya Gate is a separate issue. If that is the blocker, use the Episode 3 gate guide instead of assuming an achievement remedy will unlock the next episode.
Source and review date
Reviewed October 17, 2026. The exception list and pending-fix distinction come from the developer’s Upcoming Bug Fixes and Updates notice, rechecked through the official feed. The planning sequence is editorial guidance, not a claim that a fix has shipped or that old progress will automatically unlock every achievement. Ratatan guides →
