The mod crashes with the newest version of MooFluids, because getCurrentUseCooldown() is now called getNextUseCooldown() and setCurrentUseCooldown() is now called setNextUseCooldown() and so on. Is there any chance for an update?

Can you please provide a link to where you got Moo Fluids with this change? As far as I know, is only on Github and that is why there is no support for it.

Ah ok, I see... I needed to change something in MooFluids's code (I think it was the Hwyla support) and downloaded the latest source code from its repo. That's where I got this version from... So this is fixed, because I didn't know, this change isn't live. Sorry for the inconvenience!
P.S.: I made a fixed version of this mod myself for me :)
