Yes, and I did read somewhere that you have to be 1024 blocks away to make a new destination. But it did really frustrate me that I could not ever get back to my base until I get killed by a hostile mob, or by taking fall damage, so now I have A full inventory of netherite and no way of getting back to my base!
The trouble is though, when I exit that portal, I end up in the place where I first put the old nether portal.
This happened to me as well.
No, its very different. as i said, ill add some pictures soon. My PC is having some trouble loading the game.
