I was watching a Youtube video, and the guy said that, when you first enter the Nether, you should break the portal and put it in the "right spot", which I assume is the overworld coordinates divided by 8? And he said you should do this because otherwise it would cause "All sorts of problems."
What problems does he mean?
I'm still a noob as to how Nether portals link and stuff, but I assume he's referring to something related to that.
