I think it's how the Yalta conference works, and that's why I almost never sign it as USSR. The only way to not have that strange state transfering after the conference (I've seen a lot of times how nobody touched Konigsberg, it remained as THIRD REICH with both East and West Germany present, and only after week or two it was annexed by West Germany as colony state) is not agreeing with Yalta. So, if you want total control over puppet "true" Germany - don't go for Yalta. If you, however, decide to agree with capitalists, don't try to do anything with Third Reich itself, because it will be taken by these two "artificial" Germanies.
