I am still seeing this happen on some corpses. The most 'lively' seem to be ones where the enemy was killed with fire or radiant damage and resulted in a 'crispy' corpse. That may or may not have anything to do with it though as I have seen normal ones slide too. Overall, it seems to be improved but it is still happening. Before, I could find myself having to hunt down entire battlefields of escaping corpses to loot them. Now, it seems to be limited to one or two trying to get away in most cases.
