In several of my games I have been able to reproduce a bug with Ifan as a ranger.
In the prison level with the silent monks standing along the walls if you use Ifan cast enrage, sneak, snipe, and are able to kill a silent monk in one hit before combat starts. Turn based combat will initiate with no enemies in combat. The combat is removed if you save, and reload but is present again as soon as you kill another silent monk in the same fashion.
Here are a couple screen shots:
