OK, for kingdom creation I assume. Can you subsequently add it separately? I could use a save. There may be a database problem with the province, and either I fix that or hardwire an exception into the code. Good catch.
UPDATE. I just ran a test case as Prussia and Austria, creating an alliance. During the March 1805 economic phase, Prussia created Poland and then ceded Poland to Austria. Austria then selected West Galacia and clicked the Create Kingdom button. Both East Galacia and West Galacia were added to the kingdom of Poland. So I think the database is fine? Perhaps your game had Austria controlling enough Poland provinces to create the kingdom itself and that's where East Galacia was not added. Did you try selecting East Galacia again and clicking the Creat Kingdom button and it still failed to add? I could use a save of that to see what might be the issue.
