I was running along a concrete wall that is too high to vault over attempting to vault over it at a spot where the rising ground level would allow. The wall intersects with a mound of dirt. The mound of dirt is difficult to walk on and after attempting to vault over the dirt and the wall my character became stuck against the wall. I am unable to move in any fashion (i.e. rotating while standing or crouched or rolling while prone) with the exception of changing stances.
