I was making some drying racks for leather when I noticed 'memories of pain' flavored branches were not applicable as construction material, as it told me,' you have no applicable building material for this construction site.'
I am using amber client if that is useful to know.
(edit) I noticed that some flavored sticks work and others don't. The focused 'green' sticks that the recipe shows that it will use seem to have something to do with it not being usable.
