When ever I do go to the nether it teleports me to the nether, as it should but when I do go back in to get back home it takes me to the copper dungeons and when I try to go back in the portal it just takes me back to the nether again.This goes back and forth until I die to respawn back to my base.I don’t know what to do because when I first made my portal it wasn’t like this,until I died in the nether and it respawned me back to my base, i decide to go back it for my stuff that I lost, until it took me back to a different area in the nether .which was the place where the bug started to happen with the copper dungeons.
Now when I try to make a new portal the same things just happens.
I don’t think this is a bug. I’m pretty sure its caused by your portals not linking.
