after clicking on water, bottle return 'water bottle' AND - 'Uncraftable Potion'.

ThirstyBottles-1.12.2-1.1.4

Hello, thank you for the report. What mod is the "Uncraftable Potion" from?

vanilla minecraft, after implementing new potion mechanics with changing water bottle to potion with NBT tag "liquid type minecraft:water". Uncraftable Potion is a placeholder for potion with empty tag.

I've updated the mod to apply the correct NBT data to the item. This should fix the issue and mod conflicts.
