I once put my Baryonyx on wander because it was in a pen, because I wanted it to be sorta like Jurassic park and later that night I heard the music that plays when you’re getting attacked. Little did I know, the Rex broke my dino pen that the Baryonyx was in. It wandered off. I was so sad because it was a high level Baryonyx. It happened on day 53. Later, on about day 70 I found it attacking piranhas. I was on my Allosaurus taking a little hunting trip. So from my experience, never put a dino on wonder, even if you want to it to mate. All you have to do is just enable mating, not wandering.
