If you scale an object with a sensor, the sensor is not scaled with the object. The sensor size seems to be absolute, it is always the default one which means the object will likely stop working if you do not use its default size.
Concrete examples:
Bed of nails (try double size, now it can't pop balloons)
Cactus
Exit
Probably other objects (?)
You can also see this easily by placing these objects in the editor, scale them, then activate debug drawing and start the simulation.
