Annoying problem with Collisions....

I have two objects that needs to interact via Collider and OnTriggerEnter2D. OnTriggerEnter2D tests for object tag and if it is happy it does something…Everything works like it should in editor, however, when i build it for Windows - there is no interactions. Unity does not detect anything…

I’m not sure what to ask, so - where should i look?

Apparently, problem was in Unity ( 2017.3.0f3 ) itself…after restarting Editor and rebuilding project, everything started working…

Help…

I have 6 fixed gameobject each one has a script when it collides with another one is destroyed, I have 6 prefabs of balls that fall to the scene, when those prefabs collide with some of the gameobject I want the score to increase, I have a script but it increases separately Each gameobject I need to increase the score in general.
