I'm able to do a wild dino wipe. I've actually done it twice. I've also went on massive killing sprees as well, in the rex spawn areas and still no luck. I guess I'll try again. I really want to be able to find and tame a tek rex without having to spawn one in. It really takes the fun out of the challenge of doing it yourself. I save things like that for Minecraft. Lol.
Thank you for the help. If there's anything else that might help, please let me know. Thank you again. ?
