I am currently trying to tame a Rex, but now after I won the fight and it has become passive towards me it still continues to ravage around and kill the wild dinos in the area, isntead of going for the baits I either drop right next to it or even shoot it with my crossbow from father away, even though the icon showing that it can be fed is there. Also I can't even pet it. Is there anything I can do to complete the tame other than just forcetame it?
