Why doesn't your geopolitical map of the world reflect the reality of 2019? Under which international documents does Crimea belong to Russia?

There wouldn't be a problem. There are like 3 people in the world that would look deeply in to assume the creator is pro Russia because they... showed them controlling land they control (legally or not). This is like saying games like hoi4 could get in trouble for showing Germany controlling Poland in 1943.
