I found the enemy lord and beat him up, but when the screen with the capture dialogue was supposed to pop up, the greeting screen popped up instead. Can't take him prisoner, can't finish quest. I got a save right before the fight. https://mega.nz/file/edN1kKgI#3Lcsbwl04F0hDiOWjMDmvG2V-XnYbxqukg4dI3MMJ4Q
