This is a simple mod that changes how the player handles water and lava fluids in the world.
There are only 2 changes and they are the following:
Water - Cannot place water source blocks. Instead the water dissipates shortly after placed.
This aims to promote the player to create water channels to move the water around and also plays a significant role when choosing a spot for a base.
Lava - Completely not acquirable via bucket.
Lava contraptions should be built only where lava is present.
These changes work well with mods that provide mechanical ways to acquire/store fluids, which require some extra effort compared to the normal way of carrying them in buckets.
Acknowledgment: This mod ports functionality from the Better Than Wolves Mod, which was created by FlowerChild and is currently maintained by the CE Team. Link to the original mod -> here
