I started up a server recently. Every time we go through our only portal and then try to come back, a new portal spawns in the overworld! Since portals link up, we get sent out to the new portal every time. We partially destroy all the new portals. So now there's this graveyard of nether portals that have been creating themselves. (If that even makes any sense) I hope I can get some help for this one, I couldn't find any info anywhere else!
