All are bugs preventing progression.

Mackerel - Big
Flatfish - Big
Redfish - Big
Quest - Lost Glory (Halfdan doesn't interact)
Opals stuck on map (can turn of icons, but that still feels incomplete)
Treasure Hoards (3 locations that are lootable though not loot shows up)
Mysteries - Fabric Offering and the guy stuck in the warehouse in Lunden
Fishing - Can't get fishing done due to the extremely low window to be able to get it done in. Fish disappear during rough waters)
No Swordfish
Can't avenge players death. Haven't seen an opportunity. Ever.

I'm done with everything else...now to grind out the gear upgrades....

@novirtu3 You should be able to get big redfish off the dock at Stavanger.

@novirtu3 Big Flatfish
Big Mackerel
So, Fishing hut deliveries because of those two fish
Swordfish, because of those two fish
4 opals
Avenge 10 players

@novirtu3

1. Big mackerel, flatfish, eel (red fish can be found no problem, in fact the big ones can spawn near the pier of the starting village in Norway)
2. Same that I cannot get the Swordfish greatsword because the above big fishes do not spawn.
3. Same that I cannot avenge any dead players (I could do that in AC Origins no problem)
4. The in-game Codex, missing 1 People, 1 Faction, and 1 Location
5. Completion in Ubisoft Connect showing only 93.99% when I have finished the game and all side activities on the 3 regions (except for the fishing shack challenges due to the big fishes not spawning)

@imaginaryruins What platform are you on? I'm on Xbox. I'm showing 94.98% in Ubisoft Connect.

@jcar4327 Same. Xbox One.

I didn't collect all opals though but I highly doubt it is relevant to the in-game completion, since I didn't do that in AC Odyssey but Ubisoft Connect shows 100% for my Odyssey completion.

@imaginaryruins yeah, I don't think opals matter either. Just wondering why we have different percentages on the same platform.

Do you have all the xbox achievements?

@jcar4327 I'll add that I was at that percentage before doing 80% of the hoard maps. I just got all of those done but the glitched one in Euverscire (?) and it didn't change my percentage.

@jcar4327 All achievements (1000G) completed.

Oh that reminds me, I have 3 treasure hoard maps not yet touched because they are bugged/glitched. Still, I doubt they contribute to the completion rate.

@imaginaryruins Yeah, I don't think they do. That's basically what I was getting at because I was already at the 94.98% before I did barely any of them.

@imaginaryruins I think it's got a lot to do with that missing faction, person, location.

I got the bug where i cant complete the order. I did everything except the hunter and fishing challenges.
No more wealth to collect or mysteries to solve. Got Mjolnir, Excelibur and Odin`s spear.
I am stuck at just 91% of completion and have no clue what to do to get it up to 100%.
And i have 2 Treasure hoard map bugs aswell.
Got the Quiver Bug aswell but with no way of solving it.
Also the Yule festival quest bugged : The case of the missing ale, no way for me to complete it.

@jcar4327 I'm not sure. I already cleared the entire maps of Norway, England, Vinland, Asgard and Jotunheim, so I have no idea what entries in the Codex I am missing. How could an entire faction be missed? I highly suspect the in-game Codex has the wrong no. of entries (of course I could be wrong).

Big Flatfish
Big Mackerel
Eurviscire treasure hoard does not show up (Nothing glowing)
Oxenefordscire treasure hoard map stays in inventory after looting

We should have a secret mission/quest for beating the 6 Drengr. I have asked on player support and waiting for a response.

After 28 - "CE-34878-0" errors, (the most in any game that I've ever played since I started gaming in the mid-80s) and with just over 200 hours of gameplay, I'm a "Viking Legend". Honestly, I only completed what was necessary to get the Platinum trophy, and even then I wasn't sure if the game would allow me to complete it. Yeah, it's that bugged to cause that much doubt.

I just had a general question, there was an Opal on some shelving in an isolated house in a field - but there was no way I could pick it up, is that a glitch or maybe part of another side mission ?

@prodigurl Yes, that would be east of Walden. There will be three others in Snotinghamscire that will also be glitched. As I know you are early in the game I will give a general description but not an exact location unless you ask for it, or you can check out this thread:

Unable To Loot & Clear Opal "Opal Bug" | POST HERE | Ubisoft Forums

General locations in case you don't want to get into that thread: floating in the air in western Snotinghamscire, in a creek bed in a town, on top of a mountain.

@imaginaryruins
opals only purpose is to be able to get stuff from their real money store. So it doesnt serve any purpose beyond that really

I have the stone man mystery still to complete, its the only thing in the whole game left to do but it appears to be bugged, instead of completing the quest the little girl just keeps repeating for the stones to stay still, really hoping it can be patched so I don't miss out on the platnium
