nullable vector2 does not want to become a null

[Dmitry Savosh]

I use nullable vector2 (Vector2?). When I set it to null, it becomes null, but in next Update it returns the last value. So, I cant set it to null. This behavior works as described only if I watching the value in the inpector. If i close inspector, everything works as it should.

I use default unity serialization.

I'm unable to reproduce this issue. Doing this in Unity 2017.3.0f3 seems to work as expected:

public class TestBehaviour : MonoBehaviour
{
    [ShowInInspector]
    public Vector2? MyVector2;
}

If you could further detail how you've come to your problem, perhaps we can find a solution?

Since the reporter states that they use default Unity serialization, Vector? is not supported, nor should it be - Unity does not support nullable serialization by default.
