The Simple finishing kit requires vials of linseed oil but the UI lets you see what vial of linseed oil is made of and that you can “craft” it but the scribe does not know the base recpie of creating linseed oil so you create nothing. Luckily this does not use your materials but idk if this is a bug and wether the scribe can craft linseed oil or not
