On Ark Genesis on PS4 I just element tamed a 140 Ferox. Took it back to base and gave it the roughly 30 element to get it to 100% addiction. I left it at back of base next to a wall then all of a sudden it died to the anti meshing system. I suspect that the animation of it changing back to its small form somehow pushed it into the mesh. Please replace it, it was pretty good stats too
