On skyblock.org i was making a hopperclock, It turned it on but accidently placed a redstone torch and it is on hyperlag mode... I cant get onto my island and i dont really want to delete my island either. If you want to get to my island its /warp bomber (dont advise it)
I rollbacked some redstone torches and a redstone. That seemed to have fixed it. There's no lag anymore. Try logging on and see if everything is good.
Your island has a lag spike for me when your clock changes, but no crashes or anything like that. Looked fine to me.
