The heraldry bonus ingredients dont increase the recipe difficulty in the simulation mode.

Image is the recipe with a "+150 difficulty" heraldry added, yet it stays on 165.

Workaround is of course just adding it manually, but it should add it automatically like it does for enchanted crests.

Can confirm. Experiencing the same issue. Noticed that this is Leatherworking and my issue is with Leatherworking as well. It is possible it's limited to that, or it's just a coincidence.

Also happens in blacksmithing. Missive and embellishments adjust difficulty fine but selecting any tier of Heraldry doesn't change difficulty

Happening with JC as well.
