I put to sleep a castoroides 150 with 32 pt in melee, then it got hit by a terror bird, lost taming effectiveness, so I let it wake up, put it back to sleep, but it somehow started with a low taming effectiveness, so I left ark for a while . when I came back it was gone. Then I put to sleep a direbear 150, by the time I came back with some kibble, a carno was eating it. Then I pretty much did nothing useful. Yay.
