Huge issue: Masses of guardians spawning in ocean biomes for no reason

[bloggy]

I have the issue that thousands of guardians keep spawning in my ocean biome. I don't know why they spawn there, but it happens.

Here is my ocean biome config file: http://hastebin.com/inuxevafun.coffee

I can't see anything wrong with it.

I am on Spigot 1.9 and TerrainControl v2.8.1-SNAPSHOT.

Any ideas?

Are you on Vanilla or modded? Cause Quark makes guardians spawn randomly in the ocean.
