Well at least my cosmetics lasted over a week. And with all the merging and leaving and rejoining games with this mode it took far longer to lose my cosmetics this time around. Didn't do anything outside the normal. Lost a match, spawned on a random island. Logged out so I could start at an outpost... Back to throwing gold into a trash bin trying to save my cosmetics I guess. Or just not decorating my ship at all. Sigh...
Not sure if it has any impact but I have been setting sail with Pirates life as it lets you skip 1 click of choosing between open and closed crew. I decided to start setting sail normally through adventure so I could wake up in the tavern and vote on athena emissary faster. Did that about 5x today and then lost my saved ship cosmetics.
