Clothing glitch in animation render?

Endlessdescent

A character's jacket is going crazy during animation after rending, but looks normal when I preview the frames in DS. I have tried removing Dforce modifier and clearing all simulation data. 
Look at the arms in particular. I'm not sure why this is happening.
