Sims 4 hair meshing problem

So I’m attempting to make cc hair for the first time and I’m having some issues I hope someone can help me with! I know cc isn’t part of the actual Sims 4 game and this site is more for troubleshooting, but I’m not sure where else to ask this... So basically, in Blender I made a hair mesh I’m happy with and everything works great when I put the mesh into sims 4 studio. Then I put it in my game and it’s just the base mesh (the Jungle Adventure hair, I’ll add photos), all my mesh additions and modifications are just not there. I’ve edited clothing mesh hundreds of times the exact same way I did this hair and everything has always worked fine.
