Ostsiedlung is supposed to happen!

[Dostav]

Even though there is such an innovation in the game for Germans, and that Slavic cultures are very distinct from German ones, they will ultimately have cultural acceptance because of the way it works. And for some reason it was forgotten to be hard-coded like English, Gaelic or Scots cultural expansions that don't care about inflated cultural acceptance. So, please add Ostsiedlung innovation having condition to German rulers so that they may settle East Germany no matter for cultural acceptance.

Made a post about it year ago, this innovation should give AI behavior modifier that increases culture conversion desire, the same for forest frontier (slavic expansion into the modern russia)
