EWG Server Crash when filling world

[Justin T]

Plugin Version: 8.0.0-Snapshot Beta 3

Spigot Username: TwiztedUnique

Issue: Server loads fine and runs well, but I am using worldborder to pre-generate the world. It went up untill 71.1% where it will crash and when I start it back up it is back at 70.8% and it basically crash loops unless I pause the world border filling process
