1. Something strange is happening in the cave with the owlbear. If the mother calls for a helper in the form of a male (legendary action), the child remains hostile after killing them and cannot be recruited in the future.
If you flee combat and return later (after long resting) the cub will be gone and can be found at the goblin camp and recruited as normal. It's still a bug, but this workaround lets you recruit this very important companion.
