I still had not done the mission, and when I went to look at the menu, it was gone.

See Known Issues Thread:

Loss of inventory after "Ambush at Sea"
Description: We are aware of an issue where players may lose some of their main inventory (weapons, outfits, mounts) and experience an unintended upgrade of Bayek's gear (Hidden Blade, bracers, etc) to Legendary after completing the "Ambush at Sea" quest and then making use of the fast travel option.
Status: Will be fixed with a future update
Important Note: Please get in touch with our support team if you experience this issue. In the meantime, we are currently preventing access to the "Ambush at Sea" quest from the Deluxe Pack in order to prevent this issue from occurring. Thank you for your patience while we correct this issue.
