Volcanoes only generate in southeast quadrant.

Plugin version: 8.0.0 (Nov 23, 2018 release)

Issue: Volcanoes are only generating in southeast quadrant (positive-x, positive-z). I pregenerated a world with a 10k radius world border. There are 30+ in the southeast quadrant, and none anywhere else.

Link to settings file (world-settings.json, possibly also biome settings if you have created your own): Default installation.
