Unity3D issue: problem with 2D Circle Colliders.
In my project there are 6 prefabs called "bucket". Every bucket has a 2D Circle Collider.
A "item" in the center of the screen is dragged by mouse and when it collides with a "bucket" a new "item" respawns in the center of the screen.
When I click on Unity3D play button everything seems to work, but when I build the project and I export it to a executable file, only 2 colliders seem to work.
After the exporting, if I try to play again the project, a collider doesn't seem to work anymore.
