Can it be reproduced?

Yes

Issue

Crafting a Liquid Helium Cooler using a Portable Fluid Tank and a Cooler Frame consumes the tank and all of the fluid in it. When crafting the Cooler with a Bucket you get an empty Bucket back, which is the normal behaviour, but when crafting with tanks they are destroyed.

Fixed!
