The epic quest line at spawn has now been gone over with a fine tooth comb. Each and every quest was completed by me, personally. A few needed id updates, but they have now been fixed. (I'm looking at you Lady Comstock!)
I know a lot of you are very anxious to play but unfortunately this update is the largest Mojang has ever released. It takes a considerable amount of time for developers to catch and iron out the bug and get all the plugins working 100%.
Spigot have released several development builds but they are not yet fit for public consumption, We will continue to follow the situation and work on a test server behind the scenes so you can guys can play ASAP!
