I'm not even sure if there's anything EMC can do about this, but here goes... When generating new chunks far out in the Frontier, I've come to a landmass that seems to have been generated improperly. Like two different patterns were being used, and the met unexpectedly. The result is like taking cross sections of two different parts of the world and slapping them together. The last time I saw this was on a private server that suffered large amounts of lag. I'm not sure if this is fixable, but I'd like to find out.
This is a side effect of the Survival Update. There was an issue with Spigot that caused the world seed to change every time the server was restarted. (Before Aikar fixed it.) So any land that was newly generated during the period where it was an issue would be affected.
