I have redeemed the the pirate armory pack, obwandiyag's war club, and the assassin pack in ubisoft club but none of them are unlocked in-game. They all say "get from ubisoft club". All the weapons require you to finish sequence 5, I'm part way through sequence 6 now.
The Ubisoft Club items should be available after completing sequence 6 not 5. This appears to be an error in the description.
If you are still missing any items after completing sequence 6 then please submit a support ticket and we will look into this for you.
Please provide a small description of the issue and attach screenshots to show which items are locked and to show which sequence you are up to in the game.
