My wife and I ran into an issue with the owlbear cub on the PS5 version. After interacting with the mother and cub in the cave the first time, the mother didn't die and the cub didn't appear at the goblin camp even after several long rests. We cleared the goblin camp after reading the owlbear mother would die from an infection later after all goblins were killed. Nothing did happen though, so we then killed the owlbear mother, but now the cub is stuck in an infinite loop eating his mother.
I made exactly the same descisions on the PC version and everything went correctly. The owlbear mother was killed by goblin raiders, the cub taken to the camp and then freed.

What could cause this bug and is there a potential work around?
