Describe the bug
The list of genes is not visible with JEI in the FTB evolution modpack. And since no tutorial is available I don't understand the principle of having the flight gene. I have the 3 other genes notified but how can I get the flight gene?

The mod currently only has native EMI support, but I don't know why that would make the gene items not show up in JEI. Those are put in the creative tab, not anything specific to EMI.

To get the flight gene, you just need to get the 3 required genes and then also inject the flight gene. When you get a gene, it checks if you have all requirements, and then removes it if you don't.
