Sidle in Nameless Pass right near the start gets character stuck then dead

Climb up next to the Cottage with the decapitated body in the bed > go up and round to the cave. Next to that cave there is an option to sidle and a ‘shiny’ but when I sidle I get half-way along and it comes out of the animation and the only option is to jump off and die or logout and back in and it resets the character right next to the cave entrance.
