Because it needed a fresh restart. There was a lot of lag and some players were duping and abusing (if I am correct) so Cyp (the owner) decided to reset it. It's way better now.
Noobcroo is an owner too!!! I think the leaderboard was a good idea but i think the #1 spot, Clerklol, is a hacker. no offense and why is this under the help section?
Skyblock was in need of a reset for many reasons. After awhile, pretty much any game-mode needs to be reset. One big issue was with /warps - People were able to make unlimited amount of warps. - People were making death warps. - Unable to delete warps There were also a lot of glitched in items that were interfering with the server's economy. Skyblock now has a lot of new additions and is very different than it was before. The official reset thread is located here: http://www.mineverse.com/threads/skyblock-reset.110404/ Hopefully this answers your question. If you have any other questions or concerns do not hesitate to ask. Closing
