I hate it when that happens. Happens to me too in certain areas.
Hey VioletDeath2, if this happens again, could you try restarting your game and see if the creature moves outside the Sanctuary?
I restarted the game, and it was still there.
Also, then that messed up, I uninstalled and re-installed the game.
You can see the dino is there then the sanctuary goes on top if it. I closed the game and restarted but it’s the same.
I’ve seen it too, same problems
