Hello, I've generated a new 1.8 map on spigot then loaded it into MCEdit to make some changes, when I re-added it to Spigot the server kept crashing, stopping then restarting again giving this error. http://pastie.org/9750525 Another person had the same issue http://www.spigotmc.org/threads/solved-bukkit-createworld-new-worldcreator-string-not-working-in-1-8.36642/
I've reported the issue to MCEdit, but this issue could occur at other times and cause big trouble as there's no way to fix it, I ran region-fixer multiple times and it detected no corruptions in the map.
The issue doesn't occur in vanilla 1.8 minecraft server, here's a screenshot of how it looks in vanilla. https://imgur.com/DPXWiTk
