The armor textures for a handful of armors are displaying incorrectly in-game. The Byzantine Greek, Iberian, Egyptian, and maybe others are having issues with textures not fully loading in. This issue is most noticeable when looking at the capes, but affects the entire set of armor. Rather than loading in at the true resolution, I believe the armor is simply loading the distant texture for the armor, or at least a lower resolution variant. I caught the issue on PC, and am playing at the highest settings, so it is not an issue with needing to turn up texture quality. Furthermore, there is also a thin blue/purple line on the newly added Ealdorman's Armor. It may be intentional, but I figured I'd add that in just in case.
The image file sizes are too large to upload here, so attached is a link to an Imgur post with my images. For the first issue both screenshots are at the same angle and distance from the camera, though at slightly different locations. I noticed the textures load in correctly in a very small spot located just outside the fishing hut in Ravensthorpe.
