I'm currently experiencing a lot of difficulty figuring out how to empty the water from the liquifier. I've tried shift clicking with an empty bucket, downloading other mods for their fluid tranfers, tried every connection and direction possible, with no result. Putting H2O will produce the liquid form, but I cannot by all means, utilise, nor remove it.
I'm using the 1.15.2 version.

On Volcano Block 1.0.37, you can put milk in it, but there's no recipe to process it and you can't extract it.

On Material Energy ^5 : Entity blood can be added but not removed

I no longer plan on supporting 1.15, but this has been fixed in 1.16, thank you for reporting.
