Guild Wars 2

And although upon returning to the original two i have kept the progess, i now have zero learnt recipes. I understood that all your receipes saved?

They are supposed to stay. Did you make sure that you didn’t have a different crafting profession selected in the crafting tab?

Any recipes you acquire and scribe are now account bound and not only that character but all of the other ones should know them. Also, you get some recipes automatically upon acquiring any profession, so you should have those at least. The fact that you have zero means that, as fellyn said, maybe you have something incorrectly selected? If not, it’s definitely a bug.
