I had a green carnotaurus, it was powerful and had it's mount, once i got into the swamp trying to farm meat and prime meat with him,then a titanoboa that came out of the trash made me fall asleep, the carno was just in front of me, im sure it dind't died, (because i had my mesopithecus too) but it just vanished from existence and i don't even have it on my list of tamed dinos, why?
