I also found this problem too. I have log in to my server on afternoon, and everything are working normal at my house. But when I log in again in the evening, this bug happen. My house turn dark, other area in my house' garden too. It happen to only some chunks, not all. And when trying to replace the torch/jackolantern or place new one, it's become light. I run the server for a group of Minecraft fans in my country. So this bug impact more than just me. I hope the core of the game update to fix this bug soon. Thank you.
This pic from my strip mine which impact a lot from this bug.
