Started a new character on Valguero after being away for 3+ years.
Made a little thatch cottage in an area by the water, seemingly easy going with a few herbivores wandering around. Using the Immersive Taming mod, tamed a level 135 Ankylosaurus that became 200 something. Named him Spike and set him to wander as I think they can gather that way, and I was no where near the saddle yet.
A level 80 T Rex came out of NOWHERE and ate my best friend and bashed my cottage in right before I logged off. I died then led the Rex away, salvaging most of my progress except for Spike. He didn't seem that he attacked the Rex as much as he should have - I was thinking with the level difference he probably should have won.
So next time going to start again... probably just try to tame a Pteranodon when the Rex isn't looking, and fly to a better place to build a wooden house.
