Fairly sure everything for Vinland is intended, finding the Apple of Eden and leaving it in that region leads to future lore in some of the other games. Arriving to Vinland not being able to take your built up gear explains the need for collecting a region related set of gear. It is a shame that post-quest there is no carry over between zones having made Vinland safer but that would mean adding extra content rather than leaving the mechanic as if the player hadn't completed the Vinland saga. Some mechanics just have to be copped on the chin unfortunately, there's worse things than this in the game currently.

Also stuck at 94%.

Confirmed 100% cleared:

• Main story
• Order memebers slain
• Mysteries, Wealth and Artifacts for all 5 areas
• Reached power level 400 (currently Mastery level 77)
• Hunter's hut deliveries and legendary beasts (currently bugged on head display and only Elk of Bloody Peaks is displayed in longhouse)
• Thor's armor set and Mjolnir collected
• Excalibur collected
• Completed delivering Yanli's 4 deliveries
• All Orlog dice games won statistics screen shows 20 (Could be I missed 1 far off one)
• Caught each breed of fish at least once with a fishing line (This is a PS/Xbox achievement)
• Slid for 150m in the snow (Also a PS/Xbox achievement)

There are a few things that have been buggy that I've tried to complete that could be worth that last few percent for me, they are:

• Haven't been able to do 3 fish deliveries due to fish not spawning, Flatfish (Big), Sturgeon (Big) and Mackerel (Big) I've read people having similar issues
• Oxenefordscire Treasure Hoard animates collection but map remains in bag without any item reward
• Eurvicscire Treasure Hoard doesn't appear in location at all (Recall not reading the map until after fighting the Drengr in the same location, not sure if that helps)
• There have been some miscellaneous console achievements I've not bothered with since they aren't on PC and would otherwise be difficult to track (Random things like be thrown 30m by a Destroyer or Housecarl)
• The "Stinky but Deadly" PC achievement, from what I've read the swordfish is simply not in the game
• The "Hall of the Slain" PC achievement, again apparently bugged and not recording avenging player deaths; though there is a trackable statistic for this in Uplay
• Am strangely missing from my database Codex 1 location (22/23) 1 person (71/72) and 1 faction (9/10) 165 hours into gameplay I am hard pressed to think of a single part of any map I haven't been physically at (except a few far off ocean areas) and assume this is part of future dlc with the Codex numbers just visable now

This is all I can think for now, there were a few drinking games nearing the end of the main story I just didn't bother to complete in or lost, the statistics screen does record those wins and betting is only available if you haven't won a particular contest so although I doubtful it could be a part of getting to 100%

Just an edit. Found Sturgeon (Big) After a little time and research, they have a chance to spawn alongside Bream on the West coast of Folcanstan in Cent. They wont always spawn but from the docks along shore South until the small enemy camp if you see Bream there is likely 1-2 Sturgeon (Big) in the area, I reccomend fish hooking them as big fish can disappear if trying to bow fish. There has also been slight glitches were fish will appear to spawn after fast travelling to an area then disappearing, I experienced this when trying to get this fish.
