This is iether a suggestion or a question.
The UU matter is used to replicate things such as iridium ore. But you can't (or I don't know how to) get Iridium in the first place to duplicate. 
Plus I liked the old system better. maybe the liquid could be turned into a goo or solid. Alternatively you could have a sort of crafting table that used the goo to craft things not previously owned similar to the old system but still using the liquid.
Please contact with response or solution! Thank you!
