Title pretty much says it all - anytime I unlock a new recipe in research ('Require Thaumcraft Research' = True), I have to reload my world / re-log in order for the item to appear in JEI at all.

I'm sure it's just a matter of updating JEI when I complete a research entry. Last I heard, there's nothing fired on Thaumcraft's API end for when I right click on the discovery - but you can always use the sound played event to re-poll the player's currently unlocked research.

Or, it could be none of this, and you already know exactly what it is and I'm just rambling on.

Anyways.
❤️ your work :D

The research requirement is a bit hacky/buggy right now, so I have it disabled by default.
I made a request here Azanor/thaumcraft-5-api#6 which would make the feature work better. Until that's in, I recommend keeping 'Require Thaumcraft Research' false.

I have completely disabled the 'Require Thaumcraft Research' feature for now.

I decided to go about this a different way, and just show all recipes and mark the ones that are not researched.

Beautiful!
