So i was just digging for my new PK map and when suddenly i reached bedrock.Because i was in Creative mode i was able to break it.When I broke the bedrock the void appeared underground.It was blue.I don't know how this happened because when I dig my void is always black and it takes about 10-20 seconds for me to dig down and find it.This only took 2-3.If you know why this happened please comment!
