The error of the sensor ancient light.

At this time I was again on the sensor sunlight, it has not happened before, I know this for sure, but now (figure 1) light sensor is activated from any light source, in earlier versions of 13w05a I tested whether the sensor work сонечного of light in the darkness (night) and with a number of standing block light dust. The sun light was not working, now I came across this error purely by accident, when I just wanted to make light, running from the sensor solar lights at night, then I saw that it shuts down at night and turn on the day (this should not be, after all the illumination works from the torch, which either works or does not work from the sensor sunlight), then I поэксперементировал and it was so (figure 1). Immediately get the following (figure 2) as can be seen lamp is operated in complete darkness from the sensor sunlight, which operates from the lamp, it turns out the cycle (for a start I lit the lamp). The sun light works in complete darkness, I remind, the room must have either a broad roof, or be completely closed.
