Why Didn't It Unlock?
Work the checks in order before assuming a bug. A missing mark or a definition change is far more common than a broken achievement.
- Confirm the exact requirement, not a similar-sounding one.
- Confirm the required unique entities or count, not just any progress.
- Confirm the requirement still matches the current game version.
- Allow for the platform or game trigger to register the action before retrying.
Only follow restart or reload advice when a known issue confirms it for the current version.
