Overlapping not working

I’d wish you were right but this is my total Setting now:

See that the object class has physics enabled. I have the assumption that this causes something, cause my enemy class is controled by vector calculation and nothing is being simulated.

the object on the other Hand has an initial Impulse and torque. objects do collide with objects and interact accordingly, but at that same Moment it does not print any message for overlap Events.
