Guild Tabbard and Trinimac Motif Bug

Astanphaeus

The first image shows my armor without the guild tabbard, the second shows it when I put it on. I'm getting this brown texture taking up the side of my chest instead of the texture of the motif with the colors that I chose. The brown also appears around the neck. I don't know if this is happening with any other motifs, but it is happening with my Trinimac's light chest.

Certain helmets and guild tabards mess up the appearance of textures on Trinimac-style light shoulders.

Some examples:
Xivkyn Light Headpiece --> Max Brightness White textures on the shoulders
Molag Kena Helm --> Matte Dark Grey textures on the shoulders
