Annoying bug regarding light level

[Radu]

This is an easy to reproduce bug:
1. Fly with the carpet above mountain, at daytime.
2. Save the game.
3. Load the game

You'll notice that it looks like it's night, only that the clock indicate the proper time. Sleeping until the next morning won't help, if that happens you'll have an eternal night (however a torch will function properly).

Hope this helps.
