I hade a Rex lvl 10 i was lvl56 but ...i went to manage save data and i came to when i was lvl 28 but then there was no way to come back so I tried but that got me at lvl 1 😨😨😨 . There should be manage save data on every LVL. If the makers of ark are seeing this please do so. I used wooden dino gate if the Rex can not reach it is ok nothing should come behind it .
