Black Flag Resynced Sync Not Registering: 100% Completion Fix

The fix for Black Flag Resynced’s sync tracking bug is a manual save-and-reload workaround, not a patch, because there’s currently no way to replay a finished quest and force the synchronization menu to check it off. Players are reporting that the “Complete the quest” objectives for missions like Mister Walpole, I Presume? and The Fireship stay unticked in the Animus synchronization menu even after the mission plays out and rolls into the next one. This guide covers the symptom, the quests people are naming, the workaround that reportedly gets the tick to register, and an honest read on how much time to budget for it.

The Animus synchronization menu is where Black Flag Resynced tracks every objective needed for full completion, grouped into categories like “Journey” with sub-entries such as “It’s Not About Need.” In that entry, the second objective is to complete the quest “Mr Walpole I Presume”. Players report finishing that mission normally and progressing the story, only to open the menu later and find the box still unchecked. One player described it plainly: there isn’t a way to go back and replay it to try to get the trigger for that Animus flag. Because full synchronization is the game’s stand-in for 100% completion, a single stuck tick blocks the entire milestone regardless of how much else you’ve cleared.

Most of what’s known comes from player threads rather than official channels. One player says they finished the quest twice on separate save files and the synchronization menu still wasn’t updating, calling it the only thing stopping them from reaching 100 percent. Another, much further into the campaign, laid out just how isolated the problem is from actual progress: they were nearing the end of the game with the full Mayan armour already, having finished all the Templar Hunts and fully upgraded the Jackdaw, with every location on the map completed, yet the missing tick alone would stop them getting 100% completion. The obvious fix — reload the mission and do it again — isn’t available here. The remake changed movement and mission design in several ways, and the ability to replay older missions has been removed entirely. That single design choice is exactly why this particular tracking hiccup turns into a hard wall instead of a five-minute redo.

This sequence is pieced together from multiple player reports describing the same pattern working for both Mister Walpole, I Presume? and The Fireship. It’s not guaranteed and it isn’t an official fix, but it’s the only method anyone has actually reported success with so far.

The reason this workaround makes any sense comes down to how players believe the game stores synchronization data. According to reports, the Animus synchronization tracking is account-wide rather than tied to a specific save file, so starting a new game, speedrunning to the same completion point, saving before the trigger, and reloading until it registers can get the flag to catch — and once it does, you can go back to your older, further-along save and the completion carries over. A separate thread describes the identical logic independently, noting that sync data is account-wide rather than save-specific, which is why starting a new save file, speedrunning to the broken quests, saving before finishing them, and completing them again is worth trying. None of this is documented behavior from Ubisoft — it’s an inference players have made purely by testing it and watching it work, which is exactly why this article treats it as a report rather than a confirmed mechanic.

There’s really one method with reported success, and a few fallback options depending on how much the missing percentage bothers you.

Ubisoft hasn’t detailed a specific reward tied to hitting full synchronization in this remake, so treat this as an open question rather than a confirmed list. Series tradition suggests full completion typically ties into the platinum trophy or completion achievement plus a cosmetic reward for Edward, alongside the satisfaction of clearing every branch of the Journey menu — Templar Hunts, location sync points, ship upgrades, and story missions together. Templar Hunts specifically are missions where you collect a series of keys that unlock a Templar Armor set for Edward, described as one of the more powerful armours in the game, which gives a sense of how much of the completion checklist sits outside the story missions themselves. Until Ubisoft documents the exact 100% reward for this remake, don’t assume it matches the original 2013 release beat for beat.

Myth: This Is Confirmed as a Known Ubisoft Bug

It isn’t, at least not publicly. There is no mention of this sync tracking issue on any official Ubisoft known issues page or patch notes seen so far. Every detail in this article, including the workaround, comes from player reports on forums, not from a developer statement confirming root cause or a fix timeline.

Myth: You Have to Beat the Whole Game Again to Fix It

Also not accurate based on what players describe. The workaround only requires speedrunning a new save up to the specific broken quest, not replaying the entire campaign, since the goal is just to re-trigger that one completion flag, not to relive every mission.

Myth: This Breaks Achievements or Trophies Permanently

There’s no indication of a wider achievement-tracking failure at launch — this looks like a sync menu display issue tied to specific quest triggers, not a systemic problem with the achievement or trophy layer itself. Players affected are specifically citing the synchronization menu checklist, not missing PlayStation trophies or Xbox/Steam achievements popping incorrectly across the board.
