I'm not sure if this is an issue on Realms only, or also in single player.

In the morning, as the sun rises, some daylight sensors appears to reach intensity level 2, retract to 1, and then reach 2 again later. The behavior is inconsistent. I can't really figure out a reason this might be happening. The daylight sensors are at different angles relative to a building, and have different levels of shade. All in all, I have 16 sensors that require a distance of 2 redstone dust to power a contraption, and every morning 1 or 2 of them will activate, deactivate, and then activate again without apparent reason. It is not the same 2 every morning.
