Can you post a screenshot of your kingdom options, similar to mine?

That should make it easier to find out what exactly happens. Can you also say which subscription you have?
With my setup, I got 4 games in a row with no error.
Of course, note that having 10 Allies cards means 4 landscape slots is not useful. Since the game only ever looks at Allies cards, it will never produce a landscape other than an Ally.
