I built sort of a secret underground storage for my diamonds & other important loot. But, after crafting my own conduit, i decided to flood it with water. This wasn't the result that i was hoping for, the water is murky, cloudy & even has rendering glitches. Even with a Conduit.
It's 100% filled with water sources, i even doubled checked using the fill command.
The biome is a plains biome.
