Trophies and achievements checklist
The official Steam achievements post still answers the baseline questions players keep asking, and Ubisoft's public bug-reporter now also exposes a live King of the Castle unlock issue. This page separates the tracked issue from community-only fort-order guesses.
What the official achievements post confirms
Verified: as checked on Thursday, August 20, 2026, Ubisoft's official Steam achievements post still says the achievement list is the same across Steam, Xbox, and PlayStation. Verified: it also still says all achievements are available on any difficulty, none are missable, and you do not need an active connection to earn them after the one-time install connection.
What the official issue tracker now adds
Verified: Ubisoft's public bug-reporter now exposes ACBFR-2063 for King of the Castle not registering after capturing all forts. That does not turn every missing unlock into a verified game bug, but it does make achievement-status tracking a current player-help task on this route instead of a community-only rumor.
- Verified: Ubisoft's public issue title names King of the Castle Achievement Not Registering After Capturing All Forts.
- Reported plus disputed: public trophy and forum chatter includes both false alarms caused by a still-missing story fort and unresolved cases from players who say they already cleared the relevant content.
- Missing: Ubisoft has not yet published a standalone fix note, retroactive unlock note, or fort-by-fort audit checklist for ACBFR-2063.
Which named cleanup clusters matter most
Verified: the official visible list now names the cleanup clusters that matter most for route planning, which makes this page more useful than a generic trophy-warning note.
- Dilettante points to Great Inagua manor art and equipment completion, not to a missable story branch.
- All Hands On Deck ties officer completion back to the current /officers/ route.
- Zero Waste points to restored map pieces, which keeps Treasure Dealer and fragment demand attached to /kenways-fleet-yellowed-map/ rather than a copied coordinate dump.
- Ship This, Devil Of The Caribbean, and Collective Madness keep Jackdaw upgrades, legendary ships, and Kenway's Fleet inside the same late-game cleanup cluster.
What still is not safe to overclaim
Missing: the official Steam post does not publish a mansion-slot checklist for Dilettante, a verified map-piece timing table, a full officer unlock roster, or step-by-step hidden-achievement solutions. Missing: Ubisoft's current ACBFR-2063 public state still does not prove the exact trigger for every King of the Castle failure. Reported: community and video guides are actively trying to fill those gaps, but this site will not turn their fastest-method claims into verified facts until a stronger first-party or directly tested packet exists.
Suggested route order
Inferred: the safest cleanup order is still to finish the main sequence gates first, recruit officers as they open up, keep manor and collectible progress notes during normal exploration, strengthen the Jackdaw before heavy fleet and legendary-ship cleanup, and only then chase the remaining hidden or endgame achievements. The official no-missable rule means this can stay a route-planning page instead of a panic guide, while the live ACBFR-2063 tracker keeps King of the Castle in status-watch territory rather than checklist-certainty territory.
Questions
Are any Black Flag Resynced achievements missable?
No. As checked on Thursday, August 20, 2026, Ubisoft's official Steam achievements post still says no achievement can be missed during the adventure.
Is King of the Castle currently tracked by Ubisoft?
Yes. As checked on Thursday, August 20, 2026, Ubisoft's public bug-reporter exposes ACBFR-2063 for King of the Castle not registering after capturing all forts.
Do difficulty or online status change achievement unlocks?
Ubisoft's official Steam achievements post says all achievements unlock on any difficulty. It also says you do not need an active connection to earn them after the one-time install connection.
Does the trophy list still depend on multiplayer?
No. Ubisoft's official FAQ says Black Flag Resynced does not include multiplayer, and the official Steam post says the same achievement list applies across Steam, Xbox, and PlayStation.
Does this page verify the exact Dilettante cleanup method?
Not yet. The official Steam post confirms Dilettante is tied to filling the Great Inagua manor art and equipment slots, but it does not publish the exact completion packet. Community shortcuts stay reported-only until a stronger first-party or directly tested source packet exists.
Does the public King of the Castle issue prove every missing unlock is a real bug?
No. Ubisoft's public ACBFR-2063 issue proves the achievement is officially tracked, but public player evidence is still mixed and Ubisoft has not yet published a final fix note or a fort-by-fort audit checklist.
Should achievements change my early route?
Yes, but lightly. The official no-missable rule means you can avoid panic routing, but it still helps to track officers, manor progress, maps, fleet, ship upgrades, and legendary ships early so the late cleanup stays organized.
