#Broken / Unsupported Recipe Types

There recipe types are currently broken / aren't supported:

Item > Gas Conversion
Item > Infuse Type Conversion
Thermal Evaporation
Nucleosynthesizing
Centrifuging
Activating
Liquifier
Oxidizing
Condensentrating / Decondensentrating
Painting
Pigment Mixing
Pigment Extracting
Reaction (PRC)
Separator
Washing
Fission Reactor (There's a mod for this!)

For now, use event.custom for these.

These have no recipe types:
