About this Mod
FloodedNether
A mod that replaces (almost) every single air pocket in the nether with boiling hot water. Don't worry, you won't burn in it.
Warning
Already generated nether chunks will not fill with water. If you remove this mod, then newly generated chunks will not fill with water.
Also, PLEASE do not break/put any blocks right next to a lava ocean, because it WILL lag your game
