It's probably related to the book button. maybe its position is calculated/updated in a strange way. Anchoring to normal buttons works fine, so it's probably not something I can fix.

its a strange one as when you press the recipe button the other button does move its just when the inventory is closed. i did try to anchor to the extreme sound muffler and the curio button with the same results

I ran into the same problem and came to the conclusion that for some reason, if you open the inventory, open the recipe book, close and open the inventory, the buttons IDs change. That is, if you close the inventory with an open recipe book and reopen it, it opens like a different layout with different buttons, but the ones that were manually created remain.
