Windows .exe No Head, Arms or Left Leg on Model

[NOCK]

So when I push E and bring up the inventory, my character doesnt have a head, any arms, or his left leg...
It's not a shader issue because its gone on normal too. Tried searching for similar problems, no results. Also restarting did not fix it.

*edit* DW20 pack

Are you using Optifine?

Are you using Optifine?

yes I figured out that whatever version I was using was wrong and just removed it because I dont need any FPS boost anyway.
thank you.
