LiquidsFixer [1.14.X - 1.16.X]

Control which liquids can flow in your worlds and even sources (Water-logged blocks, water plants).
You can enable and disable per-biome and per-world.

All your worlds are automatically added when the plugin load and set to disable liquids flowing.

With this plugin, you'll can enable liquids flowing in certain biomes like in ocean, plains etc...

By default, flowing is disabled in all biomes and worlds.

To enable it in a biome, just add the biome you want in the config and set all to false or only the ones you want, then liquids can flow in this biome.
Biomes list: https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/block/Biome.html

To enable flowing in a world, set all to false or only what you want.
