So I Purchased the Expansion, and started up a Save file. Trying to start it crashed the game so I downloaded the fix, Which worked. Since then, I have learned like 5 encrusts recipes. But they are not in my book. I have seen screenshots that have a toggle between encrusts and crafting, but that option isn't in my game. I am pretty sure this is a bug. I don't need any additional tool since they are profession specific? Also. Clicking Secret recipe shows recipes that I have learned across all disciplines, even when I don't have the tool selected or the tool at all in my inventory. Quite annoying to find what I am looking for... now I have to go through dozens (hundreds?) for tinkering, smithing, and wandcrafting just to find the alchemy recipes I am looking for. It is faster just to stay in the alchemy tab.
Not really a bug - you don't have access to the new features in old saves, helps keep the stability up also.
