In Witcher 3 I'm fairly sure I've gotten all the Witcher diagrams of the 3 schools, griffin, cat & bear. I decided to go for the ursine armour set. I've made mastercrafted ursine boots and chestplate, though I'm not give the option to create enhanced gauntlets or trousers.
Is this because I have previously created enhanced ursine gauntlets/trousers and sold them? (If so, I don't remember.)
