What
ObjectArrayList is O(n²) for .contains. Since Fluids have a meaningful identity, it's better to use a HashSet.
This only matters if there are FluidIngredients that use a (tag with) a large number of fluids.
Implementation Details
Change to HashSet
Outcome
O(n) dedup
How Was This Tested
Game compiles and runs
