I left my nest with a baby pack member and got killed by predators. (recently left cell stage.) I went back a few times until they were dead. only had a new pack member to help on the last two tries. then I saw one of my species standing there with bugs around it. clicking it did nothing, I couldnt interact with it except for throwing a stick at it (which it didnt react to). other creatures acted like it wasnt there. it just stood and looked at me and acted curious. it didnt even turn around. I even walked right through it- no collision. I saved and exited to menu then went back in. it was still there, but it went clear for a second, waved, and walked back to the nest, though still couldnt be interacted with. it only disappeared for real when I migrated.
