I installed CK2Plus, and later, when I played vanilla, almost all of the domain shields (kingdoms, duchies, etc.) were replaced with black. The only exceptions were the HRE and ERE and a few of the duchies under them. Dynasty CoAs, both regular and from the DLC, still worked. I uninstalled CK2Plus and deleted its saves from the directory but the problem persisted. I checked the flags folder under gfx and all the flags that aren't there in the game look fine. What's going on and how do I fix it?
