In 1.19.2 your mod cause bucket duplication when water is placed.
stackablefixes-1.19.2-1

When you use a water bucket to place water on the ground, you have now two buckets.
The bucket was crafted normally with 3 iron ingots then filled with water at a river.

And this was tested with no other mods? Because repeating the same experiment with only this mod doesn't cause duplication.
