Hey guys

I just found a 1 Star wolf and managed to tame him, (there was an another regular wolf in the Pen but he somehow disappeared)

I remember like a year ago people talking about the "tricks" to tame those 1/2 star wolves because they would disappear if you go too far away from their pen. And even tamed I need to make those 1/2 star wolves breed in order to have their babies to be "safe" and no longer disappear for good if I leave the area. Is this still a thing ?

Lastly, can I breed a 1 star wolf with a regular wolf and hope to get a 1 star pup ? Or should I try to look for an another 1 star wolf so I have a duo and then breed them ?
