I have a crude rectangle sprite with a box colider 2d, and a circle sprite with rigidbody 2d and circle collider 2d, as seen in the image below. When I click on the red rectangle, it moves up fairly quickly a little more than the diameter of the circle.
If this occurs from the position show, or with the circle any further right than it currently is, the circle appears to fall down onto the yellow box almost instantly, hugging the side of the red rectangle. If I let the circle go a little more onto the red rectangle then it is pushed up correctly. Why is the circle falling off the red rectangle from this position, and how can I prevent it from acting like this?
