I've got a library that adds a milk fluid since it's a somewhat common thing mods add or use: https://github.com/TropheusJ/milk-lib
FabricaeExNihilo adds it's own, and registers a provider to the milk bucket here.
This causes a crash with my library and any mods that use it. There's 2 solutions:

• use milk lib. I can't imagine the transition being difficult. The library is meant to be jar-in-jar'd and the repo has instructions. Bonus of only 1 milk fluid.
• register with FluidStorage.combinedItemApiProvider instead. Pretty sure it will function identically.

original issue: TropheusJ/milk-lib#5

I don't think so. I'll ask DH if they can look into it

Did this get fixed?
