can't be done. you will gave multiple flax in the inventory. if i use them a at the same time, have at least 3 flax. you can move KID's mod above the CC just to be safe that it is loading. if you ran a debug test on the inventory, you should show several flax. i am sure you are aware that the flax do not always interchange. whichever mod made the flax is the 1 to use to process it. same thing happens with some other items also depending on mods you use. CC maple sap is not the same as PINE mod nor KID's.
