1. Yeah, that's currently a really annoying bug. But Early-Alpha is Early-Alpha and I believe Rocket said himself(Correct me if I'm wrong) "Alpha is for adding features, and Beta is for Bug Fixing". 2. Some servers give really low FPS for some reason, try another server, it may be better. 3. Its not a bug, there are 4 cycles of night time, eventually the map will be illuminated by moonlight.
