Same problem here. After being able to play "The High Life" for about 2 days, the game has downgraded itself to V 11.1 by downloading a 450 MB "update". When I start the game, the "The High Life" icon is greyed out, saying I would not own this content. But that is untrue because I bought Season Pass 3 right when it became available. When I verify the installation, it takes long and then just says "all fine". No download of DLC 9, no upgrade to current game version. Waited soooo long for this, payed for it, can't play it now, because of the 7 quadrizillionth bug. Anno 1800, the best Anno ever, but so annoying with its tons of game-breaking and game-denying bugs.
