Here. This Might help with the bukkit issues. As for my opinion, I do agree that lite feels like beta and will feel that way for some time. But some day it will have mods that are not Alpha (cough EE3 chough!) and will work cohesively. For now it is quite sulky but some day, hopefully soon, it will not.
