So this has never happened before, the owlbear didn't show up in the goblin camp... there is a chicken in his place. I leave the grove, deal with the cultists and go to the owlbear cave, ive always left the mother alive and went about exploring the area, the blighted village, the whispering depths, the dodgy cellar and then wrapped up the Kagha situation. Long rested several times, then made my way to the goblin camp. The owlbear has ALWAYS been there every other playthrough... now its a chicken. I tried to go back a few saves and long rested several more times before entering the goblin camp nothing. Still a chicken! The owlbear mother and cub are still in the cave!
Is it a bugged save? If I go to a save before the cave will that fix it? Or is a new playthrough better? Grrr
