I played a lot of ark on pc, I was surprised how seemingly well it worked as a mobile game until I started taming (single player). tames disappear once you leave their render distance. I downed a ptera, went back to base (after making sure it was safe) came back and it was gone. I rage quit then later logged back in, the ptera re-rendered in... this happened 2 more times with different tames but I couldn't get them to render back in. too bad, had lots of potential.
