A while ago when I was still kind of a noob there was an alpha raptor near my base. It was out of render distance, but as I adventured onward and got the metal past where it spawned, the alpha slowly wandered past the river and toward my base. Eventually i decided to search for the bane of those darned raptors, and all sources pointed to the Trike. I got around 5 of them, made them into a living barricade, and convinced myself that they could kill the Alpha if it ever did come. However, with my spyglass on my pteranodon I saw that the raptor had even more health than my Bronto, and became worried again. Since I was on mobile, I looked more and found out that you could use the “Tidy Save” feature, which would kind of reset the wild creatures that weren’t in render distance, so the alpha disappeared. I still believe that my Trikes could’ve taken it down now.
