With the following code the observer will detect loading of areas where it is placed.
We need to restore signal generated by it before the area was unloaded.
Observer movement and atomic clock (one observer watches another) fails without this often.
But it WILL cause wrong single signal for all other cases, and I hope it's nothing.
After all, why it can't detect the loading of areas, if we haven't a better solution...
