Texture mapped incorrectly in game [FIXED]

I am having a weird issue where a piece of CC I am making looks fine in blender and S4 studio, however when I test it in game the texture isn't mapped correctly. I've attached a screenshot with what the object is supposed to look like (how it looks in S4 studio)

I've made a lot of CC and never encountered this problem before ??

Edit: Nevermind! I inspected the mesh and there were some hidden faces that hadn't been unwrapped onto the UV map. Fixing them solved the problem.
