While playing through a pack I made for myself, I started to notice certain ocean mobs never spawned anywhere in my world. This includes the cachalot whale, frilled shark, hammerhead shark, mantis shrimp, mimic octopus, blobfish, giant squid, and orca. I created a creative world to see if it was an issue there and it was as well. I tried deleting the alexs mobs toml file in order to fix this. It worked for the creative world, but not for my survival world. Is there any way I can fix this?
