Quest completion bugs and 100% sync status

Official status today

Verified: as checked on Monday, August 17, 2026, Ubisoft's latest broad public launch-status post is still the August 2026 Known Issues refresh that followed Title Update 1.0.6 on Tuesday, August 4, 2026. Verified: Ubisoft's public bug-reporter has now widened the completion-tracking story beyond the earlier ACBFR-482 Journey Synchronization issue, which is enough to justify a focused support-status page instead of burying this exact player task inside the broader launch hub.

• Verified: Ubisoft's public issue ACBFR-482 still covers Journey Synchronization progress failing to credit completed quests for some players.
• Verified: Ubisoft's public bug-reporter now also exposes separate quest-completion entries such as ACBFR-2642 for multiple bugged Animus Synchronization objectives, ACBFR-2805 for The Sage's Buried Secret and The Other Cheek not registering, and ACBFR-4403 plus ACBFR-4501 for The Sage's Buried Secret completing but not tracking.
• Reported: current public Steam completion threads now name player-facing failures such as Mister Walpole, I Presume?, The Fireship, Very Little, But Something, and The Sage's Secret while players describe being blocked from 95 percent or 100 percent cleanup.

What this page can and cannot confirm

Verified: Ubisoft's official Steam achievements post still says no achievements are missable, the list is shared across platforms, and difficulty does not change unlocks. Missing: that official trophy baseline does not mean the current quest-credit bug family is fixed, so this page stays a status and escalation surface rather than pretending to be the final completion checklist.

• Verified: the official no-missable rule still stands.
• Missing: Ubisoft has not yet published a public fix note, replay-quest feature note, or standalone Help article for the completion-tracking family.
• Missing: no public official completed-quests-list answer currently explains how to audit finished quests after a tracking failure.
• Missing: the site still does not have the complete verified milestone dataset needed for a trustworthy /completion-checklist/ capability.

Best next step if your journey or quest tile will not credit

If your save is blocked by a quest or synchronization tile that will not mark complete, the safest publishable advice is to stay inside the official-status lane. Retest on the newest build, capture the exact quest name and where it fails, then report it against the closest public Ubisoft issue page instead of trusting forum replay recipes as if they were official fixes.

• Verified: use the current 1.0.6-plus-August-4 official state as your baseline before reporting a still-open completion bug.
• Verified: include the exact quest name, platform, and whether the failure appears under Journey, Synchronization, Animus Hub, or trophy cleanup.
• Verified: if your case matches the broader progress-not-crediting family, cite ACBFR-482 or the more specific public quest-completion issue page that matches your symptom.
• Unverified: community suggestions such as manual-save loops, replaying an old save, or starting a fresh file remain player reports, not verified Ubisoft fixes.

Why this is a page and not the checklist capability

This route is publishable because it answers a live player-help task with first-party issue tracking and clear claim-state boundaries. The completion-checklist capability is still in research because the site does not yet have a complete verified milestone, collectible, and progression dataset strong enough for a trustworthy local planner.
