Here I thought, "Na, something like that wouldn't happen."
Then I looked and thought, "Oh...well. Nevermind."
Yes, I have the same trouble as you. Well, I don't have the bog, and maybe a few others. I do have more options than just day, morning, night, and evening, such as space, void, and fog. Of course, I tried koding something like that in, but to no avail. While I wish I could offer assistance by bringing back the assets. But digging into this topic: viewtopic.php?f=22&t=185
there may be a way to get the skies back by downloading a game with those assets. I could easily be wrong, though.
Don't get discouraged! We may be few, but there's still enough to keep the game (and our interest in it) floating.
