plesis and other dinos not moving

Making a new map and having an issue where a spawner i have spawns plesi’s and sharks atm on the same spawner, the sharkes swim around but the plesis just sit there idle. anyone know why this is or how to fix it? i know making custom spawners break dino mods but since i dont care if my map works with annunaki and i work very closely with the dino overhaul guy this wont be an issue for me.

Make sure your ocean is deep enough, then plesi will move, same for the mosa.

thanks, the issue turned out to be my landscape had to be lowered as they were already on the bottom and instead of them using depth to calculate inside the volume they used World Z…
