Some (mostly) visual stuff that irks me. I do not deep-dive in balance as I feel others got me covered there already.
-Oathsworn weapon models are missing from the forge.
-Tigers and Lions have the same green eyes as Jade Tigers.
-Goblin Peacekeepers if mounted on an eagle are floating heads!
-Dwarf Oathsworn units lack beards as well as the monk making them unplayable! Book of Grudges-worthy!
Long unfixed things:
-Mystic and Reaver cultures and now Oathsworn have a preset colorscheme that forces itself onto randomized factions as well as independents and mob races.
-Some cloaks have sharp edges that stick out of where they are supposed to end. There is also a common clipping issue though this mainly with animations in diplomacy screen which are rarely ever seen.
-Dragon genders are still forced to whatever is given to them at first. I make it a habit to fix a certain dragon's gender every time I start the game but whenever I boot it up again it's been reset to male.
